Part A A small car collides with a large truck. Is the magnitude of the force experienced by the car greater than, less than, or equal to the magnitude of the force experienced by the truck? O equal to less than O greater than Submit Request Answer Part B Choose the best explanation from among the following: O The truck has more mass, and hence the force exerted on it is greater. O The massive truck exerts a greater force on the lightweight car. O Action-reaction forces always have equal magnitude. Submit Request Answer
