Suppose a shot-putter who takes 1.25 s to accelerate the 7.19-kg shot from rest to 15 m/s raises it 0.725 m during the process. What is the power output P, of the shot-putter, in terms of the variables given in the problem statement. (Do not include the power required to accelerate his body.) Calculate the power output, in watts, of the shot-putter. (Do not include the power produced to accelerate his body.)
