Two skaters each of mass 50 kg, approach...

Two skaters each of mass `50 kg`, approach each other along parallel paths separated by `3m`. They have equal ad opposite velocities of `10 m//s`. The first skater carries a long light pole, `3 m` long, and the second skater grabs the end of it as he passes (assume frictionless ice).
a. Described quantitatively the motion of the skaters after they are connected by the pole.
b. By pulling on the skaters reduce their distance to `1m`. What is their motion then?
c. Compare the `KEs` of the system in parts a. and b. where does the change come from?
