Explanation:
A 150 g cricket ball moving at a speed of 12 m s-1 is
hit by a bat and turned back at a speed of 20 m s-1.
The duration of impact is 0.01 s. What is the average
force exerted on the ball by the bat?
Given :
m = 150
g = 0.15 kg,
u = 12 m/s^-1
v= -20 m/s^-1
t = 0.01 s,
To find :
F = ?
Solution :
As,
➸ F x t = Impulse = change in momentum
➸ F x 0.01
➸ m (v - u)
➸ 0.150 (- 20 - 12)
➸ F = -0.15 x 32/0.01
➸ F = - 480N
