Answer:
okay it's nun of ur bussiness love
Explanation:
Pushing, pulling is the answer
Answer:
A
Explanation:
This is because distance traveled (i.e. displacement) is the integral of the velocity function, and velocity is the first derivative of the displacement function. To put this in perspective, the area bounded by a curve can be found by taking the integral of the equation of the curve, taking values on the x-axis as limits.
Answer:
kinetic energy
Explanation:
a certain amount of energy is transferred by the kick. The ball gains an equal amount of energy, mostly in the form of kinetic energy.
Explanation:
The attached figure shows data for the cart speed, distance and time.
For low fan speed,
Distance, d = 500 cm
Time, t = 7.4 s
Average velocity,
![v=\dfrac{d}{t}\\\\v=\dfrac{500}{7.4}\\\\v=67.56\ cm/s](https://tex.z-dn.net/?f=v%3D%5Cdfrac%7Bd%7D%7Bt%7D%5C%5C%5C%5Cv%3D%5Cdfrac%7B500%7D%7B7.4%7D%5C%5C%5C%5Cv%3D67.56%5C%20cm%2Fs)
Acceleration,

For medium fan speed,
Distance, d = 500 cm
Time, t = 6.4 s
Average velocity,
![v=\dfrac{d}{t}\\\\v=\dfrac{500}{6.4}\\\\v=78.12\ cm/s](https://tex.z-dn.net/?f=v%3D%5Cdfrac%7Bd%7D%7Bt%7D%5C%5C%5C%5Cv%3D%5Cdfrac%7B500%7D%7B6.4%7D%5C%5C%5C%5Cv%3D78.12%5C%20cm%2Fs)
Acceleration,
![a=\dfrac{v}{t}\\\\a=\dfrac{78.12}{6.4}\\\\a=12.2\ cm/s^2](https://tex.z-dn.net/?f=a%3D%5Cdfrac%7Bv%7D%7Bt%7D%5C%5C%5C%5Ca%3D%5Cdfrac%7B78.12%7D%7B6.4%7D%5C%5C%5C%5Ca%3D12.2%5C%20cm%2Fs%5E2)
For high fan speed,
Distance, d = 500 cm
Time, t = 5.6 s
Average velocity,
![v=\dfrac{d}{t}\\\\v=\dfrac{500}{5.6}\\\\v=89.28\ cm/s](https://tex.z-dn.net/?f=v%3D%5Cdfrac%7Bd%7D%7Bt%7D%5C%5C%5C%5Cv%3D%5Cdfrac%7B500%7D%7B5.6%7D%5C%5C%5C%5Cv%3D89.28%5C%20cm%2Fs)
Acceleration,
![a=\dfrac{v}{t}\\\\a=\dfrac{89.28}{5.6}\\\\a=15.94\ cm/s^2](https://tex.z-dn.net/?f=a%3D%5Cdfrac%7Bv%7D%7Bt%7D%5C%5C%5C%5Ca%3D%5Cdfrac%7B89.28%7D%7B5.6%7D%5C%5C%5C%5Ca%3D15.94%5C%20cm%2Fs%5E2)
Hence, this is the required solution.
