Solve 480N

Answer 1

Answer:

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

Answer 2

F=480 is answer
