Two gliders are on a smooth, level air track. The final speed of glider R is greater than the final speed of glider T (i.e., VRf > VTf). The masses of gliders R, S, and T are different (ms>m7>mr). Gliders A, R, and T are free to move after the collision, but glider S is stuck in place on the track. In each case, the system is defined as the two gliders.

The horse pulls the cart and the cart pulls the horse in response as per Newton third law. So the big question is, “Don’t the two forces cancel each other? How does the cart accelerate?”
