A rubber ball of mass 50 g falls from a height of 5m and rebounds to a height of 1.25 m. Find the impulse and the average force between the ball and the ground if the time for which they are in contact was `0.1s`

A

`0.5N`

B

`1.5 N`

C

`0.15 N`

D

`2.5 N`

Text Solution

Verified by Experts

The correct Answer is:
B

`F=(dp)/(dt)=(m(v-u))/t` where `v=sqrt(2gh_(2)),u=sqrt(2gh_(1))`
