Question: a car slides across an icy road and crashes into...

Question details

A car slides across an icy road and crashes into a stopped car. The two cars eventually become entangled and slide across the ice together after the collision, eventually coming to rest some distance away.

T/F The collision process is itself elastic. KE is dissipated only during sliding afterward.

T/F The momentume of the two car system immediately after the collision (as they begin to slide across the ice as a unit) is the same as the momentum of the incoming car immediately before the collision.

T/F The KE of the two-car system immediatley after the collision is the same as the KE of the incoming car immediately before the collision.
