Question: A playground merry-go-round of radius R = 1.80 m has a moment of inertia I = 255 kg •m2 and is rotating at 8.0 rev/min about a frictionless vertical axle. Facing the axle, a 24.0-kg child hops onto the merry-go-round and manages to sit down on the edge.
Question 1: What is the new angular speed of the merry-go-round?
If possible just a brief explanation how you got the answer?
At t = 0 the current to a dc electric motor is reversed, resulting in an angular displacement of the motor shaft given by ?(t) = (240 rad/s)t ? (21.0 rad/s2)t2 ? (1.60 rad/s3)t3. At what time is the angular velocity of the motor shaft zero
