If a 64 kg sprinter can accelerate from a standing start to a speed of 10 m/s in 3 s, what average power is generated?

Answer 1

Power=w/t=f*d/t= f*∆V

Power== f*∆V=[(64kg)(9.8m/s^2)]*[(10m/s-0m/s)/3s]=???

Answer 2

Work = Change in kinetic = 0.5M*V^2.
P = W/t = 0.5M*V^2/t = (0.5*64*10^2)/3 = 1067 J/s. = 1067 Watts.
