Question

A small mass of 0.5 kg is traveling with a speed of 4 m/s, while a large mass of 2 kg is traveling with a speed of 1 m/s. Which has more momentum?

1) The smaller mass

2) The larger mass

3) They have the same

Can individual objects in a system have momentum while the momentum of the combined system is zero?

1) Yes

2) No

A piece of putty and a tennis ball with the same mass are thrown against a wall with the same velocity. Which object experience a greater impulse from the wall or are the impulses equal?

1) Putty

2) Ball

3) Equal

Answer 1

Small mass momentum =mass *velocity=0.5 *4= 2 kgms/s

Large mass momentum = mass * velocity =2 * 1 = 2 kgm/s

So the small mass momentum and large mass momentum are same.

Answer is 3) They have the same

Yes,they can have. If the objects are moving in opposite direction after collision,the combined system momentum is zero but they do have individual monents.

Answer is 3)equal impulse
