A ball of mass 0.15 kg is dropped from a height 10 m, strikes the ground and rebounds to the same height. The magnitude of impulse imparted to the ball is (g =10 m/s 2 ) nearly:
Text Solution
Verified by ExpertsThe correct answer is:
Velocity while hitting the ground
As it goes to the same height it will return with sane speed.
So change in velocity v-(-v) = 2v
Change in momentum or impulse
= 2mv
=4.2kgm/s
