Question
A man of mass 100 kg stands at the rim of a turn table of radius 2m, moment of inertia 4000 kg. The table is mounted on a vertical smooth axis, through its center. The whole system is initially at rest. The man now walks on table with a velocity 1 m/s relative to earth
Through what angle will it have rotated when the man reaches his initial position relative to earth
The correct answer is:

A string is wrapped several times on a cylinder of mass M and radius R. the cylinder is pivoted about its axis of symmetry. A block of mass m tied to the string rests on a support so that the string is slack. the block is lifted up to a height h and the support is removed. (shown in figure)
If M = m, what fraction of KE is lost due to the jerk developed in the string
