Newton's Third Law Practice Test

A 0.30 kg puck slides and collides with a stationary 0.50 kg puck on nearly frictionless ice; they are in contact briefly before separating. During contact, puck 1 exerts a force on puck 2 and puck 2 exerts a force on puck 1. How do the magnitudes of these forces compare?

A student pulls a sled with a rope across level snow at constant speed. The rope exerts a force on the sled, and the sled exerts a force on the rope. At an instant while the sled is moving, how do these interaction forces compare in magnitude?
