Aplayer hit a serve in a racket sport that was clocked at 129 mph. how much work did he have to do on the 2-oz ball to get that speed?

1 × 10² J

Step-by-step explanation:

Given data

2 oz × (1 kg/35.274 oz) = 0.06 kg

The work exerted by the player is equal to the kinetic energy (K) adquired by the ball.

K = 1/2 × m × v²

K = 1/2 × 0.06 kg × (57.7 m/s)²

K = 1 × 10² J
