Q. A turntable that spins at a constant 80 rpm takes 3.70 s to reach this angular speed after it is turned on. Find its angular acceleration (in rad/s^{2}), assuming it to be constant, and the number of degrees it turns through while speeding up.

Q. A 0.29 meter stick balances at its center. If a necklace is suspended from one end of the stick, the balance point moves 7.0 toward that end. If the mass of the necklace is less than the meter stick, why does the center point move towards the necklace?
