A large truck collides head-on with a small car. The car is severely damaged as a result of the collision. According to Newton's third law, how do the forces acting between the truck and car compare during the collision? a. The force on the truck is larger than the force on the car. b. The force on the truck is smaller than the force on the car. c. The truck does not exert a force on the car during the collision. d. The car does not exert a force on the truck during the collision. e. The force on the truck is equal to the force on the car.
