A batsman hits back a ball straight in the direction of the bowler without changing its speed of `12 m s^(-1)`. If the mass of the ball is 0.15 kg, determine the impulse imparted to the ball.

Text Solution

Verified by Experts

We are given: `vecu= 12 ms^(-1), v=-12ms^(-1) , m=0.15 kg`
We are to calculate, Impulse
We know that, impulse= change in momentum=` vecp_(2)-vecp_(1)= mvecv- mvecu= m( vecv- vecu)`
`:.` Impulse `= 0.15(-12-12)= -3.6 Ns`
or magnitude of impulse = 3.6 N s
