1.	a 150 gram tennis ball coming at a speed of 40 m per second is hit straight back by a bat to speed of 60 M per second the magnitude of the average force on the ball when it is in contact for 5ms with the bat is
Answer» Force = MASS × Acceleration From the question we can get the acceleration. Acceleration = change in velocity ÷ TIME This equals to : (60 - 40) / (5/1000) 20 / 0.005 = 4000m/s² 150/1000 = 0.15 F = 4000 × 0.15 = 600N

Answer»

Force = MASS × Acceleration

From the question we can get the acceleration.

Acceleration = change in velocity ÷ TIME

This equals to :

(60 - 40) / (5/1000)

20 / 0.005 = 4000m/s²

150/1000 = 0.15

F = 4000 × 0.15 = 600N
