1.During a tennis serve,the top of the raquet,which is 15m from its pivot point,accelerats from rest to a speed of 10m/s in a time of 0.10s.Calculate the average tangential acceleration and the top of the racquet and also its angular acceleration.

Tangential acceleration = change speed/time

angular acceleration= tangential acceleration / radius

what are pivots
