Chapter 7 - Linear Momentum - Misconceptual Questions: 1

Answer

Choice D.

Work Step by Step

Assume that the truck and car are part of the system. Assuming there are no net external forces, or that they act over a negligibly short time, momentum during the collision is conserved (i.e., the change in system momentum is zero). Any momentum gained by the truck is lost by the car. In other words, their individual momentum changes are equal and opposite.
