Consider a meter stick whose mass is 300 grams and that lies on ice (see representation in which we are looking down on the meter stick). You pull at one end of the meter stick, at right angles to the stick, with a force of 6 newtons. Assume that friction with the ice negligible. What is the rate of change of the center-of-mass speed $v_{CM}$? What is the rate of change of the angular speed $\omega$?

System: Stick

Surroundings: Your hand (pulling); ice (negligible effect)

$d\vec{P}/dt = d(m\vec{v}_{CM})/dt = \vec{F}_{net}$

From the momentum principle:
