You are ice skating at 13 m/s toward a grizzly bear who is in turn skating 4 m/s toward you. Your weight is 756 N and the bear is 900 N. Immediately after the collision you are moving at 8 m/s in your original direction. Neglect external horizontal forces applied by the ice to the skaters during the collision. What is the velocity of the bear immediately after the collision? Calculate the decrease in total kinetic energy of both you and the bear.
