AP Physics C: Mechanics
4.4 Elastic and Inelastic Collisions
4.3 Conservation of Linear Momentum
Two carts on a horizontal, frictionless surface collide in two separate trials. The carts form an isolated system. Data recorded before and after each collision are shown in the table.
Which row in the table correctly classifies each collision and states whether the total linear momentum of the two-cart system is conserved?
| Trial | Total Initial Kinetic Energy | Total Final Kinetic Energy | Observation After Collision |
|---|---|---|---|
| 1 | \(12\text{ J}\) | \(12\text{ J}\) | Carts bounce apart |
| 2 | \(16\text{ J}\) | \(6\text{ J}\) | Carts stick together |
