Chapter 11, Problem 43P

To determine

To find:

(a) The radius of the circular motion performed by skaters.

(b) The angular speed of the skaters.

(c) The kinetic energy of the two-skater system

(d) The angular speed of the skaters if they pull along the pole until they are separated by

 $1.0\mathrm{ }\mathrm{m}.$

(e) The kinetic energy of the two-skater system if they pull along the pole until they are separated by $1.0\mathrm{ }\mathrm{m}.$

(f) What provided the energy for the increased kinetic energy.
