1. A spinning object has a moment of inertia of 1.6 kg*m2. It is rotating at a rate of 1rad/s. If the moment of inertia increases to 3 kg*m2, what is the new rotational velocity?

2. A gas orginally occupies a volume of 0.2 m3 at a pressure of kPa. It is slowly allowed to expand until the volume of 0.2 m3 at a pressure of 100 kPa.It is slowly allowed to expand until the volume is 2.0 m3. Assuming the temp is kept constant, the final pressure will be?

3. Two people sit on a see-saw balanced at the center. One person weighs 500 N and sits 1m from the center of balance, the other weighs 600 N, where does he have to sit for the see-saw to stay balanced?
