both of theoretical mass 50 kg, are ice skating and approach each other along parallel paths separated by 3.0 m. We have opposite velocities of 1.4 m/sec each. Will carries one end of a long pole of negligible mass and I grab the other end as I pass. Assume that the friction between skates and ice is negligible. What are (a) the radius of the circle? (b) our angular speed? And (c) the kinetic energy of our two-skater system? Next, we pull along the pole until we are separated by 1.0 m. What are (d) our angular speed and (e) kinetic energy of the system? (f) What provided the energy for our increased kinetic energy?
