Question

Two ice skaters are skating toward one another. Neither skater is paying much attention, so they collide. One of the ice skaters is a large man with a mass of 122.0 kg. The other skater is a small boy whose mass is only 21.0 kg. Before the collision, both skaters have a speed of 2.4 m/s. When they collide, the man picks up the boy, and their final speed is 1.61 m/s, in the direction the man was moving. The magnitude of the force that the man exerts on the boy at the instant they collide is 777.0 Newtons. What is the magnitude of the force that the boy exerts on the man at that instant?

I have diffculties with magnitudes, any help and explanation would be great. Thank you so much!

Explanation / Answer

Newton's Third Law states that every force encounters an equal-in-magnitude and opposite force. This law is usually re-stated as "for every action, there is an equal and opposite reaction". When they collide, the force with which the man hits the boy is THE SAME as the one with which the boy hits the man
