Question

1. Two objects of different masses have the same momentum. Which of them is moving faster?
2. A boy throws up a ball with a velocity v0. If the ball returns to the thrower with the same velocity, will there be any change in (a) momentum of the ball? (b) magnitude of the momentum of the ball?
3. When a ball falls from a height, its momentum increases. What causes increase in its momentum?
4. In which case will there be larger change in momentum of the object? (a) A 150 N force acts for 0.1 s on a 2 kg object initially at rest. (b) A 150 N force acts for 0.2 s on a 2 kg. object initially at rest.
5. An object is moving at a constant speed in a circular path. Does the object have constant momentum? Give reason for your answer.

Answer 1

Q 5 it's momentum remains same as its velocity remain constant
