Block a, with a mass of 4 kg, is moving with a speed of 2. 0 m/s while block b, with a mass of 8 kg, is moving in the opposite direction with a speed of 3 m/s. The center of mass of the two block-system is moving with a velocity of:.
The center of the mass of the block-system is moving with a velocity of 1.3 meters per second in the same direction as B.
In this case, we are provided with:
The mass of block A (M1) = 4 kg
The speed of block A (V1) = 2.0 meters per second
The mass of block B (M2) = 8 kg
The speed of block B (V2) = 3.0 meters per second
Consider that block A is moving in a positive direction while block B moving the opposite way.
To find the velocity of the center of the mass of the two block system, we can use this following formula:
[tex]V = \frac{M1V1 + M2V2}{M1+M2}[/tex]
To find the answer, simply plug in all of the information that you already have into the equation:
[tex]V = \frac{(4 kg) (2m/s) + (8kg) (-3m/s)}{4 kg + 8 kg}[/tex]
V = -1.3 m/s
Because the sign is negative, we may deduce that the center of mass of the two-block system is traveling in the same direction as B at a speed of 1.3 m/s.

(c) Assume that, at t=0 s, the horizontal position of the box is x=0 and it has a vertical position of y=0. Derive an equation that describes the vertical position y of the box as a function of the horizontal position x of the box.
(d) Does your equation from part (c) agree with your sketch in part (b)? Justify your response
The equation that describes the vertical position y of the box as a function of the horizontal position x of the box is y = 1/2 x^2 + 0.5xt.
A crane and box are both initially at rest. At time t=0s, the crane begins to drive forward at a constant speed of 0. 5ms, while also lifting the box with an upward acceleration of 1ms2.
This equation agrees with the sketch in part (b) because it shows that the vertical position of the box increases as the horizontal position increases, as shown in the sketch. This equation also shows that the vertical position of the box increases with time at a rate of 1 m/s^2, which is the value used for the upward acceleration of the box.

The driver of a car travels 150 miles to reach his destination. If he travels 60. 0 mi/h for 100 miles and 55. 0 mi/h for the remaining 50. 0 miles, what was his average velocity for the trip?.
The average velocity of that driver is 58 mi/h.
How to find the average velocity for that driver?As per data given:
first velocity (V1) = 60 mi/h
first distance (s1) = 100 miles
second velocity (V2) = 55 mi/h
second distance (s2) = 50 miles
First, we have to find the time spend that driven in first 100 miles by calculate it as follow:
V1 = s1 : t1
60 = 100 : t1
t1 = [tex]\frac{10}{6}[/tex] h
Then calculate the second condition in 50 miles:
V2 = s2 : t2
55 = 50 : t2
t2 = [tex]\frac{10}{11}[/tex] h
then calculate the average velocity:
Average velocity = total distance / total time
Average velocity = 150 : ([tex]\frac{10}{6}[/tex] + [tex]\frac{10}{11}[/tex] )
Average velocity = 58.2352941176
Let round the value to 58 mi/h. Hence, the average velocity of the driver is 58 mi/h

A student is connecting three resistors of various resistances together in a circuit. In one configuration, the resistors are connected in a series. In another configuration, the resistors are connected in parallel. Explain which configuration results in a higher total resistance.
The configuration with the resistors connected in series results in a higher total resistance.
What is the difference between a series and parallel circuit configuration?A series circuit configuration is one in which the electrical components are connected end-to-end, so that the current must flow through each component before reaching the next one. This means that the current is the same through all components, and the total resistance of the circuit is equal to the sum of the individual resistances. In contrast, a parallel circuit configuration is one in which the electrical components are connected side-by-side, so that the current can flow through multiple components at the same time. This means that the voltage across all components is the same, and the total resistance of the circuit is lower than the smallest individual resistance.

Answer:
Explanation:
jjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjkkkkkkkkkkkkkkkkiiiiiiiiiikooooooooooooop
To find the average speed of the girl for the entire trip, we need to calculate the total distance covered and the total time taken.
Distance covered during running = speed x time = 5 m/s x 2 s = 10 m
Distance covered during walking = speed x time = 4 m/s x 3 s = 12 m
Distance covered during biking = speed x time = 10 m/s x 5 s = 50 m
Total distance covered = 10 m + 12 m + 50 m = 72 m
Total time taken = 2 s + 3 s + 5 s = 10 s
Average speed = Total distance covered / Total time taken
= 72 m / 10 s
= 7.2 m/s

Changes in volume and density cause a gas in the atmosphere to rise as it is heated, and as a gas rises, its temperature decreases.
What is volume and density about?As a gas is heated, the molecules that make up the gas gain energy and begin to move faster. As the molecules move faster, they collide with each other more frequently and with greater force, causing the gas to expand and its volume to increase.
As the gas expands, its density decreases, and its buoyancy increases, making it less dense than the surrounding air. When a gas is less dense than the surrounding air, it tends to rise, which is known as convection.
Therefore, As a gas rises, it experiences a decrease in temperature, this is due to the decrease in atmospheric pressure. When a gas rises, the pressure on it decreases, which causes the gas to cool down.

inward and finally spins at 7.7 T rad/s.
3.
What is her average angular acceleration
during this time interval?
Answer in units of rad/s^2
According to the answer The average angular acceleration 1.3 rad/s^2.
What is angular acceleration?Angular acceleration is the rate of change of angular velocity over time. It is a vector quantity, which means that it has both a magnitude and direction. Angular acceleration is usually measured in units of radians per second squared (rad/s2). The magnitude of angular acceleration indicates how quickly the angular velocity is changing, and its direction indicates the direction of the angular velocity change.
The average angular acceleration of the figure skater during this time interval can be calculated using the equation a = (Δω)/(Δt). Here, Δω is the change in angular speed during the interval and Δt is the length of the interval.
Therefore, the average angular acceleration = (7.7 rad/s - 3.2 rad/s) / 4.6 s = 1.3 rad/s^2.

You weigh 710 N. What would you weigh if the Earth were three times as massive as it is and its radius were five times its present value? Answer in units of N
Answer:
85.2 N
Explanation:
You want to know your weight if the Earth were 3 times as massive and had 5 times the present radius. Your weight is 710 N.
WeightYour weight is proportional to the mass of the Earth and the square of the radius between your mass and the center of the Earth. The revised dimensions of the earth would multiply your weight by ...
W = k(M/r²) = 710 N
W' = k((3M)/(5r)²) = k(M/r²)(3/25) = (710 N)(3/25) = 82.5 N
Your weight would be 82.5 N.

The wavelength of the radio wave is 5.5 × 10³ m. If the frequency of the wave is 5.5 × 10⁴ hertz and the speed of the wave is 3.0 × 10⁸ m/sec.
The speed(v) of a wave is the product of wavelength(λ) and the frequency(η). We can understand this relation by the definition of the speed, which is the distance travelled by the object in unit time. The unit of distance is meter, also the unit of the wavelength is meter. On the other hand the unit of frequency is sec⁻¹. So,
Speed of a wave(v) = wavelength(λ) × Frequency(η)
Wavelength(λ) = speed of the wave(v)/Frequency(η)
Wavelength(λ) = (3.0 × 10⁸)/(5.5 × 10⁴)
