Consider the impact-relevant FBD of a car involved in a collision. Assume that, at the time of impact, the car was stationary. In addition, assume that the impulsive force F, with line of action ℓ, is the only impulsive force acting on the car at the time of impact. The point P at the intersection of ℓ and the line perpendicular to ℓ and passing through G, the center of mass of the car, is sometimes referred to as the center of percussion (for an alternative definition of center of percussion see the Mini-Example on p. 552). Is it true that, at the time of impact, the instantaneous center of rotation of the car lies on the same line as P and G?

Note: Concept problems are about explanations, not computations.
