A small car bumps into van at rest. Upon which vehicle is the force of contact greater? Which vehicle undergoes the most acceleration?

A small car bumps into van at rest. Upon which vehicle is the force of contact greater?

Are you familiar with Newton's 3rd Law? What does it say about the magnitude and direction of forces between bodies?


Which vehicle undergoes the most acceleration? From Newton's 2nd Law boils down to: \vec F = m \vec a. For a given value of 'F' if 'm' is large then 'a' is small, and vice versa.
