Question:

A soccer ball is kicked horizontally off a  

22.0

meter high hill and lands a distance of  

35.0

meters from the edge of the hill. Determine the initial horizontal velocity of the soccer ball.

Projectile:

The projectile motion is a combination of uniform motion and uniform acceleration motion. When an object is thrown with a velocity (v) then, the horizontal component of the velocity (

Explanation:

Friction is the force used to prevent 2 objects from rubbing against each other. This would mean if you rubbed your hands together you would feel the heat from the force of friction against the 2 objects namely your hands. Some things mitigate friction like water and soap. Water commonly used in waterslides reduces friction since the properties of water reduces the friction so much that you would be able to slide smoothly. This happens since wet object don't makes hard surfaces smooth. Soap does the same thing since the two objects are more slippery and can seem to get a grip on each other for friction.

Newton's Law of Cooling is a simplification based on the assumption that the rate of energy flow is proportionate to the temperature difference.

Radiative energy flow becomes essential at very high temperature differences, and this is proportional to the difference in temperatures raised to the fourth power.

Answer:

The maximum height reached is approximately 44.1 meters

Explanation:

The upward (vertical) velocity of the ball = 29.4 meters per second

The equation of the vertical motion of the ball under gravity, is presented as follows;

v² = u² - 2 × g × s

Where;

v = The final velocity of the ball = 0 at maximum height

u = The initial vertical velocity with which the ball was thrown= 29.4 m/s

g = The acceleration due to gravity ≈ 9.8 m/s²

s = The height reached by the ball = [tex]s_{max}[/tex] at maximum height

∴ 0 = 29.4² - 2 × 9.8 × [tex]s_{max}[/tex]

29.4² = 2 × 9.8 × [tex]s_{max}[/tex]  = 19.6·[tex]s_{max}[/tex]

[tex]s_{max}[/tex]  = 29.4³/19.6 = 864.36/19.6 = 44.1 meters

[tex]s_{max}[/tex]  = The maximum height reached = 44.1 meters.

The maximum height reached by the ball is 43.2 meters.

Using the formula:

v² = u² + 2gH

where v is the final velocity, u is the initial velocity, g is the acceleration due to gravity and H is the height.

At maximum height, v = 0. Given that u = 29.4 m/s, g = -10 m/s (moving upward). Hence:

0² = 29.4² + 2(-10)H

20h = 29.4²

h = 43.2 meters

The maximum height reached by the ball is 43.2 meters.

Answer:

As most economies witness rapid expansion, demand for power is projected to increase significantly. Though most economies have invested in fossil fuels, renewable and sustainable sources present great possibilities for cheap and reliable electricity. One energy resource that ranks among the top renewable and sustainable sources is tidal energy.

Tidal energy or tidal power is a form of renewable energy obtained due to alternating sea levels. The kinetic energy from the natural rise and fall of tides is harnessed and converted into electricity. Tides are caused by the combined gravitational forces of the moon, sun, and earth. However, tides are influenced most by the moon. The moon’s gravitational force is so strong that it tugs the ocean into a bulge. The high and low tides create tidal currents, which are essential in the generation of this kind of energy, mostly prevalent in coastal areas.

B. The flute would usually have the highest pitch, but because the piccolo is half the size of a flute, it's higher pitched. The piccolo in C has a range from D5 – C8 which is pretty high pitched. This means that the piccolo's range is an octave above that of the flute.

C. The human ear naturally picks out higher notes, so when piccolos play extremely high, we can hear them more easily than the other instruments in a band or orchestra.

D. I'm sorry but I don't know this one.

A sound wave is produced when a medium begins to vibrate. When an entity vibrates, a pressure wave is formed, which causes sound.

When an object vibrates, a pressure wave is created, which produces sound. The particles in the surrounding medium (air, water, or solid) vibrate as a result of the pressure wave.

The vibrations of the particles move nearby particles, allowing the sound to travel further through the medium.

Hence a sound wave is produced when a medium begins to vibrate.

    The hiker (you ) is  200 m below his/her(your) starting point

b

   The resultant displacement in the north east direction is

[tex]a  = 6562.0 \  m [/tex]

    The resultant displacement in vertical direction (i.e the altitude change )

  [tex]b =6503.1 \  m [/tex]

Explanation:

From the question we are told that  

  The displacement in the morning is  [tex]S_{morning} =  (2200 \m , east) + (4000\ m\ north) + (100 \ m ,\ vertical)[/tex]

   The displacement in the afternoon is  [tex]S _{afternoon}= (1300\ m ,\ west) + (2500 \ m ,\ north) - (300\ m ,\ vertical)[/tex]

Generally the direction west is negative , the direction east is positive

                 the direction south is negative , the direction north is  positive

resultant displacement  is mathematically evaluated as  

    [tex](2200 \m , east) +( - 1300\ m ,\ west) = 900 \ m \ east[/tex]

     [tex](4000\ m\ north)  + (2500 \ m ,\ north) = 6500  \ m ,\ north[/tex]

     [tex](100 \ m ,\ vertical) - (300\ m ,\ vertical) = -200 \ m[/tex]

From the above calculation we see that at the end of the hiking the hiker (you) is  200 m below his/her(your) initial position

Generally from Pythagoras theorem , the resultant displacement in the north east direction is

      [tex]a  =  \sqrt{900^2 + 6500^2}[/tex]

=>     [tex]a  = 6562.0 \  m [/tex]

Generally from Pythagoras theorem , the resultant displacement in vertical direction (i.e the altitude change )

      [tex]b = \sqrt{6500^2 +(-200)^2  }[/tex]

=>   [tex]b =6503.1 \  m [/tex]

Answer:

1 /2 (W / g)  V^2 = KE1

1/2 *(W / 2) / g * (2V}^2 = KE2 = 1/2 (W / 2 ) g * 4 V^2

KE2 / KE1 = 2

The lorry traveling at twice the speed has twice the KE

4 times energy due to speed but 1/2 the mass

Lorry 2 has more kinetic energy than Lorry 1.

To compare the kinetic energy of the two lorries, we use the formula for kinetic energy:

Kinetic Energy (KE) = 1/2 * mass * [tex]velocity^2[/tex]

Let's assume the following:

Lorry 1 (L1) has a mass of M kg and a velocity of V m/s.

Lorry 2 (L2) has a mass of half of L1's mass, so its mass is (1/2)M kg, and it has a velocity of 2V m/s.

Now, let's calculate the kinetic energy for each lorry:

For Lorry 1 (L1):

KE1 = 1/2 * M * [tex]V^{2}[/tex]

For Lorry 2 (L2):

KE2 = 1/2 * (1/2)M * [tex](2V)^2 = 1/2 * (1/2)M * 4V^2 = 2 * (1/2 * M * V^2) = 2 * KE1[/tex]

From the calculations, we can see that the kinetic energy of Lorry 2 (KE2) is double the kinetic energy of Lorry 1 (KE1).

So, even though Lorry 2 is moving at twice the speed of Lorry 1, its kinetic energy is higher because it also has half the weight (mass) of Lorry 1. The increased speed of Lorry 2 contributes more to its kinetic energy than the decrease in mass.

Therefore, Lorry 2 has more kinetic energy than Lorry 1.
