Question
(5) Given that glider 2 is initially at rest (v2i 0), 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 2. If the collision is elastic and the mass of glider 2 is much smaller than glider 1, then glider 2 3. If the collision is elastic and both gliders have the same mass, they will actually exchange 4. If the collision is completely inelastic and the mass of glider 2 is much larger than glider 1, 5. If the collision is completely inelastic and both gliders have the same mass, then both will directly bounce back at about half of the initial speed after collision will move at almost twice the speed of glider 1 after collision. the velocity upon the collision. then both gliders will stick together and be almost at rest after collision gliders will stick together and be almost at rest after collision.Explanation / Answer
1) False
If the collision is elastic and the mass of the glider 2 is much larger than glider 1, then glider 1 will directly bounce back at about same speed of the initial speed after collision.
In a head-on elastic collision between a small projectile and a much more massive target, the projectile will bounce back with essentially the same speed and the massive target will be given a very small velocity. One example is a ball bouncing back from the Earth when we throw it down.
2) True
If the collision is elastic and the mass of the glider 2 is much smaller than glider 1, then glider 2 will move at almost twice the speed of glider 1 after collision.
In a head-on elastic collision where the projectile is much more massive than the target, the velocity of the target particle after the collision will be about twice that of the projectile and the projectile velocity will be essentially unchanged.
3) True
For a head-on collision with a stationary object of equal mass, the projectile will come to rest and the target will move off with equal velocity, like a head-on shot with the cue ball on a pool table. This may be generalized to say that for a head-on elastic collision of equal masses, the velocities will always exchange.
4) True
5) False
If the collision is completely inelastic and both gliders have the same mass, then both glider will stick together and velocity will be half that of initial after collision.
