Q. The balances read 385-g and 115-g. Both are 20 cm from each end of a meterstick. Assume the meterstick has zero mass and use torques to determine the position of the 500 g weight on the stick.

Q. At t = 0 a grinding wheel has an angular velocity of 21.00 rad/s. It has a constant angular acceleration of 21 rad/s^2 until a circuit breaker trips at 2.40s. From then on it turns during 344 rad as it coasts to a stop at constant acceleration.
