AP Physics C 2022 Exam Question 2
2. Cart 1 of mass m1 is held at rest above the bottom of an incline. Cart 2 has mass m2, where m2 > mk, and is at rest at the bottom of the incline. At time t = 0, Cart 1 is released and then travels down the incline and smoothly transitions to the horizontal section. The center of mass of Cart 1 moves a vertical distance of H, as shown. At time tC, Cart 1 reaches the bottom of the incline and immediately collides with and sticks to Cart 2. After the collision, the two-cart system moves with constant speed v. Frictional and rotational effects are negligible.
