Physics - If a Mack truck and Honda Civic have a head-on collision,

If a Mack truck and Honda Civic have a head-on collision, upon which vehicle is the impact force greater? Which vehicle experiences the greater acceleration?

Answer:

The force will be the same on the two vehicles, according to Newton's Third Law. That means the Civic, with far less mass, will experience a much greater acceleration, according to Newton's Second Law.
