I AM TERRIBLE at Y/N! Could you help explain?

Given that glider 2 is initially at rest are the statements below correct?

1. If the collision is elastic and the mass of glider 2 is much larger than glider 1, then glider 1 will directly bounce back at an almost same speed after collision .

2. If the collision is elastic and the mass of glider 2 is much smaller than glider 1, then glider 2 will move at almost twice the speed of glider 1 after collision.

3. If the collision is completely inelastic and the mass of glider 2 is much larger than glider 1, then both gliders will stick together and be almost at rest after collision.

4. If the collision is elastic and both gliders have the same mass, they will actually exchange the velocity upon the collision.

5. If the collision is elastic, the relative velocity of one glider with respect to the other is reversed by the collision.

Explanation / Answer

This is very simple just apply law of conservation of energy and get the answere.
