Two skaters each of mass 50 kg approach each other along prallel paths separated by 3 m . hey have oppsite velocities of 1.4 m/s each. one skater holds the end of a long pole of negligable ass, and the other skater grabs the other end of it as she passes. assume the ice provides frictionless surface.
(a) describe quantitativley the motion of the skaters after they have become connected by the pole.
(b) what is the knietic energy of the system?
(c) if the skaters pull on the pole so as to reduce thier separation to 1 m what are thier angular speed.
(d) what the new kinetic energy of the system?
