During your tennis serve, your racket and arm move in an approximately rigid arc with the top of the racket 1.5 m from your shoulder joint. The top accelerates from rest to a speed of 20 m/s in a time interval of 0.10 s. A) Determine the magnitude of the average tangential acceleration of the top of the racket. B) Determine the magnitude of the rotational acceleration of your arm and racket.
