4. Two ice skaters collide and hold on to each other for balance. Initially, one 620N skater was going south at 5.8 m/s, while the other, 760N skater, was going 30° north of west at 7.2 m/s a) Calculate the speed and direction of the skaters after impact. b) How much kinetic energy was lost during the collision? 620N 5.8 m/s 7.2 m/s 30° 760N
