Question:

A 1.6-kg tube AB can slide freely on rod DE which in turn can rotate freely in a horizontal plane. Initially the assembly is rotating with an angular velocity ω = 5 rad/s and the tube is held in position by a cord. The moment of inertia of the rod and bracket about the vertical axis of rotation is 0.30 kg ?? m2 and the centroidal moment of inertia of the tube about a vertical axis is 0.0025 kg ?? m2. If the cord suddenly breaks, determine

(a) The angular velocity of the assembly after the tube has moved to end E,

(b) The energy lost during the plastic impact at E.
