Mike (52.0 kg) аnd Terrаnce (86.0 kg), аlоng with several оther kids are playing a game оf “bumper kids”. They are all running around and they are wearing inflatable suits that provide protection and cause them to bounce off of anyone or anything they come into contact with. When fully inflated, the suits are spherical. Each child’s body passes through the middle axis of the sphere. Mike and Terrance collide into each other. Mike started out running at 1.2 m/s towards the right, and after the collision was knocked backwards at 4.6 m/s. If Terrance is moving at 0.5 m/s toward the left after the collision, what was his speed and direction before the collision?
