Questions and Answers

- 1.Which is the best wording to describe the conservation of momentum
- A.
Momentum before a collision is the same as the momentum after the collision

- B.
Momentum before a collision is the same as the momentum after the collision if there are no external forces

- C.
The total momentum before a collision is equal to the total momentum after a collision

- D.
The total momentum before a collision is equal to the total momentum after the collision if the total external forces acting upon the system is zero.

- 2.In explosion type collision, two static trolleys of masses 2Kg and 3Kg start to move apart (pushed by a spring between them), What is the velocity of the first trolley if the 3Kg trolley moves with velocity 4m/s?

- 3.Why does a gangstah (note new spelling) not actually fly back through a glass window when he "takes" a bullet
- A.
The bullet is travelling too fast

- B.
He might will be wearing a bullet proof vest

- C.

- B.
The earth pulls down on the gangster, and the pavement pushes up on the ganster

- C.
The ganster's mass pulls up on the earth, and the ground pushes up on the gangster.
