A ball of mass m, travelling with velocity `2hati+3hatj` receives an impulse `-3mhati`. What is the velocity of the ball immediately afterwards?

Text Solution

Verified by Experts

The correct Answer is:
A, C
Using `J=m(v_f-v_i)`
`-3mhati=m[v_f-(2hati+3hatj)]`
or `v_f=-3hati+(2hati+3hatj)`
or `v_f=-hati+3hatj`
