1. The problem statement, all variables and given/known data The cheetah is one of the fastest-accelerating animals, because it can go from rest to 3.4 m/s (about 8 mi/h) in 0.5 s. If its mass is 112 kg, determine the average power developed by the cheetah during the acceleration phase of its motion. Express your answer in watts and horsepower. 2. Relevant equations 3. The attempt at a solution v = u + at ...since the cheetah is initially at rest , u = 0 m/s therefore v = at and we have a = (v/t) Now power is defined as rate of doing work P = ( Force x displacement ) / time P = (ma x s) / t where s is the displacement s = vt P = (m) * (v/t) (vt) divided by time t finally doing all the algebra gives us P = mv ^2/ t P = (112 x 3.4^2) / 0.5 P = 2589.4 are my units wrong? but where?
