Question

A bowling ball has a mass of 5 kg hits a wall going 7 m/s and rebounds at a speed of 2 m/s. What was the impulse applied to the bowling ball?

Answer 1

the answer is 45......................

Answer 2

Impulse is given by

`Impulse = P_f - P_i`

`Impulse = 5*2 - (5*-7)`

`Impulse = 10 + 35`

`Impulse = 45 kg m/s`

So impulse given by the ball will be 45 kg m/s.
