Question

Multiple-Concept Example 7 presents a model for solving problems such as this one. A 1020-kg van, stopped at a traffic light, is hit directly in the rear by a 747-kg car traveling with a velocity of +1.78 m/s. Assume that the transmission of the van is in neutral, the brakes are not being applied, and the collision is elastic. What is the final velocity of (a) the car and (b) the van?
