a projectile is fixed from ground level with a velocity 500m/s at 30 degree to the horizontal .find its horizontal range, the greatest height and time to reach the greatest height.​

Answers

Answer:

1. 22092.31 m

2. 3188.78 m

3. 25.51 s

Explanation:

Let's split this projectile's motion into its horizontal and vertical components:

Horizontal (v_x) component: 500 * cos(30)Vertical (v_y) component: 500 * sin(30)

Since this projectile is in constant acceleration (9.8 m/s² vertically downwards and 0 m/s² horizontally), we can use the kinematic equations for constant acceleration.

Let's find the time it takes for the projectile to reach its greatest height first by using our knowledge that, at the top of its trajectory, the projectile will have a final velocity of 0 m/s before changing its direction and falling down.

Therefore, we can use the equation that contains the variables a_y, v_f, v_i, and t in order to solve for time t.

This equation is: v = v_0 + at, where v is the final velocity, v_0 is the vertical component of the initial velocity, a is the acceleration in the y-direction, and t is the time of flight of the projectile.

Plug known values into the equation:

0 = 500 * sin(30) + (-9.8)t

Subtract 500 * sin(30) from both sides of the equation.

-500 * sin(30) = -9.8t

Divide both sides by -9.8.

t = 25.51

The time it takes the projectile to reach its greatest height is 25.51 seconds.

Now we can use this time t to find the greatest height of the object, which will be the displacement in the y-direction at t = 25.51 seconds.

We can use this equation that contains the variables displacement (Δx), initial velocity (v_0), acceleration (a_y), and time (t):

Δx = v_0 t + 1/2at²

Plug known values into the equation.

Δx = [500 * sin(30)] * 25.51 + 1/2(-9.8)(25.51)² Δx = 6377.5 + -4.9 * 650.7601 Δx =  6377.5 + -3188.72449  Δx = 3188.77551

The displacement in the y-direction is 3188.78 m at half the time t, meaning that this is the greatest height of the projectile.

Now we can find the horizontal range of the projectile by using the same equation, but this time in the x-direction.

Δx = v_0 t + 1/2at²  

We will use the x-component of the initial velocity and the acceleration in the x-direction, which is always 0 m/s² assuming air resistance is negligible. Note that the time we have above (25.51 sec) is only half the total time, so we will use double this time (51.02 sec).

Δx = [500 * cos(30)] * 51.02Δx = 22092.31

The horizontal range of the projectile is 22092.31 m.

Applying the law of universal gravitation, we have

F = G m₁ m₂ / R²

where

G = 6.67 × 10⁻¹¹ N•m²/kg²

m₁ = 1.7 × 10³⁰ kg

m₂ = 5.5 × 10²⁰ kg

R = 2 × 10⁵ m

3) A 100kg man runs up a staircase
3 cm high in 5 seconds. How much

Answers

Answer:

Power = 5.88 Watt

Explanation:

Mechanical Work and Power

Mechanical work is the amount of energy transferred by a force. Its SI unit is the joule.

Being  the force vector and  the displacement vector, the work is calculated as:

[tex]W=\vec F\cdot \vec s[/tex]

If both the force and displacement are parallel, then we can use the equivalent scalar formula:

[tex]W=F.s[/tex]

Power is the amount of energy transferred or converted per unit of time. In the SI, the unit of power is the watt, equal to one joule per second.

The power can be calculated as:

[tex]\displaystyle P=\frac {W}{t}[/tex]

Where W is the work and t is the time.

The m=100 Kg man goes up a distance of s=3 cm = 0.03 m in t=5 seconds. To calculate the work done against gravity the weight is considered as the force:

F = m.g = 100*9.8

F = 980 N

The work is:

W = 980*0.03

W = 29.4 J

Finally, the power is:

[tex]\displaystyle P=\frac {W}{t}[/tex]

[tex]\displaystyle P=\frac {29.4}{5}[/tex]

P = 5.88 Watt

A bicyclist initially at rest, begins pedaling and gained speed steadily for 4.80s during which she covers 37.0m What was her final speed?

Answers

Answer:

The final speed of the bicyclist is 15.44 m/s.

Explanation:

Given;

initial velocity, u = 0

time of motion, t = 4.8 s

distance covered, d = 37.0 m

The acceleration of the bicyclist is calculated as;

d = ut + ¹/₂at²

37 = 0 + ¹/₂(4.8)²a

37 = 11.52a

a = 37 / 11.5

a = 3.22 m/s²

The final speed of the bicyclist is given as;

v² = u² + 2ad

v² = 0 + 2(3.22)(37)

v² = 238.28

v = √238.28

v = 15.44 m/s

Therefore, the final speed of the bicyclist is 15.44 m/s.

Marc was told his dinner would be ready at 18:00. He left his house at 12:00 and travelled in his car at an average speed of 45mph to his mum's house 300 miles away. Did Marc make it home in time for dinner

Answers

Answer:

No

Explanation:

No, Marc did not make it on time for dinner.

The time duration between 12:00 and 18:00 is 6 hours.

Total distance that needs to be covered from his house to his mum's house and back = 300 miles x 2 = 600 miles

Time that would be needed to cover 600 miles to his mum's house at an average speed of 45 mph = distance/speed

    = 600/45

            = 13.33 hours

The required time to cover the distance by Marc is approximately 13.33 hours. If he leaves the house by 12:00, he will definitely not get back 6 hours after. Hence, he could not have made it for dinner.

A string attached to an airborne balloon was maintained at an angle of 54 degrees with the ground. If 2.3 m of string was reeled in to return the balloon back to the ground, what was the horizontal and vertical displacements

Answers

Answer:

dₓ = 1.35 m

dy = 1.86 m

Explanation:

In order to find the vertical and horizontal components of the displacement, we can assume a right triangle. Such that, the length of string is the hypotenuse, making and angle of 54° with the base of triangle. The base is the horizontal component of displacement. And the perpendicular is the vertical component of displacement. Therefore:

[tex]d_{x} = d\ Cos\ \theta[/tex]

where,

dₓ = horizontal component of displacement = ?

d = resultant displacement = 2.3 m

θ = angle between displacement and ground = 54°

Therefore,

[tex]d_{x} = (2.3\ m)\ Cos\ 54^0[/tex]

dₓ = 1.35 m

For vertical component of displacement:

[tex]d_{y} = d\ Sin\ \theta\\d_{y} = (2.3\ m)\ Sin\ 54^0[/tex]

dy = 1.86 m


6. Why does sound travel faster through a steel bar than through a swimming pool filled with water?
Water is a denser medium than steel.
Water has a larger wavelength than steel.
Steel has a larger wavelength than water.
Steel is a denser medium than water.

Answers

I understand that sound travels faster in water then in air. Water is a liquid, and air is gas.

Water still has the ability to roll the molecules over each other (so water can flow), it has some flexibility.

But I do not understand how a solid that is inflexible can make sound waves travel faster then in a flexible liquid.

In fact, sound waves travel over 17 times faster through steel than through air.

Sound waves travel over four times faster in water than it would in air.

What is the density of the metal?​

Answers

Answer:

The density of the metal is [tex]12\ gr/cm^3[/tex]

Explanation:

Density

The density of a substance is the mass per unit volume. The density varies with temperature and pressure.

The formula to calculate the density of a substance of mass (m) and volume (V) is:

[tex]\displaystyle \rho=\frac{m}{V}[/tex]

The piece of metal has a mass of m=1200 gr. When the piece of metal is submerged in a measuring cylinder, the water level rises from 150 cm3 to 250 cm3. This means the piece of metal occupies a volume of V=250 cm3-150 cm3=100 cm3.

The density is:

[tex]\displaystyle \rho=\frac{1200}{100}[/tex]

[tex]\rho=12\ gr/cm^3[/tex]

The density of the metal is [tex]\mathbf{12\ gr/cm^3}[/tex]

A thermal cap used in certain apparatus consist of silica rod which fits tightly inside an aluminium tube whose internal diameter is 8mm at 0 degree c … elcius.Calculate what change in temperature to produce channel whose cross section equal to 1 mm

Answers

Answer:

change in temperature is a decrease by 268.734 K

Explanation:

We are given;

Temperature: T1 = 0°C = 273 K

Internal diameter; d1 = 8mm

Final diameter; d2 = 1 mm

To solve this, we will use Charles law formula since pressure is constant.

Thus;

V1/T1 = V2/T2

Where T2 is the final temperature.

Now, V1 and V2 are volume

Volume is given by: V = area x height

We are told the cross section is equal except for the diameter.

Thus;

V1 = A1 × h

V2 = A2 × h

Thus;

(A1 × h)/T1 = (A2 × h)/T2

h will cancel out and making T2 the subject, we have;

T2 = (A2 × T1)/A1

A2 = π(d2)²/4

A1 = π(d1)²/4

Thus;

T2 = [(π(d2)²/4) × T1]/(π(d1)²/4)

π and 4 will cancel out to givw;

T2 = ((d2)²× T1)/(d1)²

T2 = (1² × 273)/8²

T2 = 273/64

T2 = 4.266 K

Thus;

Change in temperature = T2 - T1 = 4.266 - 273 = -268.734 K

Thus, change in temperature is a decrease by 268.734 K

On a position time graph, the slope of a line would represent the velocity, since the rate of change represents how many meters traveled in the given time.

The larger the slope, the faster the velocity; the steeper the line, the faster the speed.

Since line B is negative, you know that velocity is negative so it automatically has the lowest speed.

Out of lines A and C, since A is steeper, you know that A has a faster speed.
