Hockey is a sport in which athletes use hockey sticks to hit a puck across smooth ice. At practice one day, three hockey pucks (all with the same mass) were sliding across the ice. A player hit each puck with a hockey stick, but not from the same direction. Each puck changed speed as a result of being hit. Use the information in the diagram to answer. Which hockey puck(s) experienced the strongest force when hit? How do you know?
