Question

Because it can go from rest to 16.2 m/s in 2.4 s, One of the fastest accelerating animals is the cheetah. If its mass is 58.0 kg, determine the average power developed by the cheetah during the acceleration phase of its motion express your answers in watts and horsepower Because it can go from rest to 16.2 m/s in 2.4 s, One of the fastest accelerating animals is the cheetah. If its mass is 58.0 kg, determine the average power developed by the cheetah during the acceleration phase of its motion express your answers in watts and horsepower

Explanation / Answer

Kinetic energy gained = 1/2 m v2^2 - 1/2 m v1^2

power = energy / time = 1/2 m v^2 / t

= 1/2 * 58 * 16.2^2 / 2.4 -> 3171.15 W

Horsepower is both archaic and not well defined ( there have been MANY different measures over the years) so it has no place on a scientific web site.
But if you use one common form the result is 3171.15 /745.699872 or "about 4.252 horsepower
