Question

6. A ball of mass 150 g is moving with velocity 12 m/s
strikes with the bat and rebounds back with velocity 20
m/s. If duration of contact between bat and ball is 0.1 s,
then find: (i) change in momentum of ball (ii) average
force on ball.

Answer 1

Answer:

Last velocity=20

Start velocity=-12

Differnece= 20-(-12)=32 Ns

32/(1/10)=320 N
