Average force exerted by the bat is

Question

A cricket ball of mass 150 g is moving with a velocity of 12 m/s and is hit by a bat so that the ball is turned back with a velocity of 20 m/s. If duration of contact between the ball and the bat is 0.01 sec. Average force exerted by the bat is 

(A) 480 N 

(B) 120 N 

(C) 1200 N 

(D) 840 N

Answer 1

Correct option: (A) 480 N

Explanation:

F × Δt = 4.8 NS

F = {(4.8) / (Δt)} = {(4.8) / (0.01)} 

= 480N.
