Hockey players "Betty" and "Sally" collide as they race to reach the hockey puck. The figure shows speed and direction before the collision, as well as the direction after the collision. Betty's mass is 55.0 kg, and Sally's mass is 45.0 kg. c) Calculate the speed of both Betty and Sally after the collision. Was the collision elastic? d) What was the force impulse on Betty (value and direction) in the collision?
