Curling is a sport in which players push large stones across smooth ice. Three curling stones that have the same mass were sliding across the ice. They were each pushed by a player, but not all from the same direction. Each curling stone changed speed as a result of being hit. Use the information in the diagram to answer.
Which curling stone(s) experienced the strongest force when hit? How do you know?

A satellite was in two separate crashes. In both crashes, the satellite had the same mass. Engineers want to know about the speed and direction of the satellite after the crashes. Why would the crash affect the motion of the satellite, and which crash caused a greater change in motion for the satellite?
