In a cricket match, a bowler piecks up a ball (0.5 kg ) from ground. He then runs to maximun speed of 5 m/s and throws the ball at a speed of 25 m/s. At the time of throwing the ball, the ball is at a height of 2 m from ground. The entire event takes 5 s to perfom. the average power delivered to the ball by the bowler is

A
