Question

If two balls each of mass 60 g moving in opposite directions with speed 3.5 m/s collide and rebound with the same speed, then the impulse imparted to each ball due to other is ____________.

Options

• 0.42 kg m/s

• 0.24 kg m/s

• 0.81 kg m/s

• Zero

Answer 1

If two balls each of mass 60 g moving in opposite directions with speed 3.5 m/s collide and rebound with the same speed, then the impulse imparted to each ball due to other is 0.42 kg m/s.

Explanation:

Impulse = change in momentum = 2 mv

`= 2 xx 0.06 xx 3.5`

` = 0.42  "kg m/s"`
