A piece of putty moving with 1 unit of momentum strikes and sticks to a heavy bowling ball that is initially at rest. After the putty sticks to the ball, both are set in motion with a combined momentum that is
A. less than 1 unit. B. more than 1 unit. C. 1 unit. D. Not enough information to say.

C. 1 unit

Explanation:

Given that the piece of putty is moving with 1 unit of momentum.

We need to find the combined momentum after putty hits the bowling ball.

As we know the principle of conservation of momentum, which says momentum before collision will be equal to momentum after the collision.

We have given momentum before the collision as 1 unit. So, the momentum produced after the collision will be 1 unit also.

d) physical means can be used to separate the components of air.
