Question

Elastic collisions: one at rest one moving, two colliding, both initially moving the same direction.

Inelastic collisions: one at rest one moving, two colliding, both initially moving the same direction.

Perfectly elastic collisions: one at rest one moving, two colliding, both initially moving the same direction.

Questions1. Was momentum conserved for all types of collisions you examined in this experiment? If not, explain the cause of losing orgaining momentum.2. Was total velocity conserved for all types of collisions you examined in this experiment? If not, explain the cause of losing orgaining velocity.3. Was kinetic energy conserved for all types of collisions you examined in this experiment? If not, explain the cause of losing orgaining kinetic energy. In general, how does the momentum after a collision compare to the momentum before the collision?5. In which type of collision was the before-and-after difference in momentum the least? In which type of collision was thedifference the most?6. What factors might cause the total momentum immediately after a collision to not equal the total momentum immediatelybefore the collision? Explain how these factors affect the momentum.7. For a head-on collision between two carts of equal mass and equal speed, what is the total momentum before the collision?8. Compare the momentum of a firecracker at rest to the momentum of the firecracker after it explodes.9. Imagine two carts, one with twice the mass of the other, that are going to have a head-on collision. In order for the two cartsto be at rest after the collision, how fast must the less-massive cart move compared to the more-massive cart?
