The cheetah is one of the fastest-accelerating animals, Because it can go from rest to 14.2 m/s (about 32 mi/h) in 2.1 s, one of the fastest-accelerating animals is the cheetah. If its mass is 50.0 kg, determine the average power developed by the cheetah during the acceleration phase of its motion. Express your answer in the following units.

Power in watts is 2400 W and in horse power is 3.218 hp.

Explanation:

Power is defined as the amount of work done per unit time. From work energy theorem, the work done is equal to the difference in the kinetic energy. Since the initial speed is zero, so the initial kinetic energy will be zero. So the work done is equal to the final kinetic energy.

As the mass is 50 kg and velocity is 14.2 m/s with time 2.1 s, then the work done will be

Then this need to be convert to horse power as 1 horse power = 745.7 W.

So, power in horse power will be

So power in watts is 2400 W and in horse power is 3.218 hp.
