A 2.60 kg steel gas can holds 15.0 L of gasoline when full. What is the average density of the full gas can, taking into account the volume occupied by steel as well as by gasoline?
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.
