Question

Two skaters, each of mass 50 kg, approach each other along parallel paths separated by 5.9 m. They have equal and opposite velocities of 1.6 m/s. The first skater carries one end of a long pole with negligible mass, and the second skater grabs the other end of it as she passes; see the figure. Assume frictionless ice. Describe quantitatively the motion of the skaters after they have become connected by the pole.

a) What is their angular speed?

c) Calculate the ration of the final kinetic energy to the original kinetic energy.
