Two carts initially move towards each other on a horizontal track, and make a partially inelastic collision. Ignore friction and drag during this brief collision.
Based solely on the information given for this collision, the two lab carts:
(A) rebound with no deformation.
(B) rebound after unsticking, with some deformation.
(C) are stuck together with no deformation.
(D) are stuck together and are permanently deformed.
Correct answer (highlight to unhide): (B)
In a partially inelastic collision, some translational kinetic energy is lost to deformation, but the two colliding objects rebound such that they are not stick to each other afterwards.
(Response (A) is for an elastic collision; response (D) is for a completely inelastic collision.)
