Consider a stick of length 1 meter and mass 600 grams lying on ice. You pull at one end of the stick, at a right angle to the stick, with a force of 25 N, causing the stick to rotate clockwise. Assume that friction with the ice is negligible. What is the rate of change of the angular speed? The moment of inertia of a rod of mass M and length L about its center of mass is ML2/12.
