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.

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
