A circular table rotates about a vertical axis with a constant angular speed `omega`. A circular pan rests on the turn table (with the centre coinciding with centre of table) and rotates with the table. The bottom of the pan is covered with a uniform small thick layer of ice placed at centre of pan. The ice starts melting. The angular speed of the turn table.

A circular turn table has a block of ice placed at its centre. The system rotates with an angular speed w about an axis passing through the centre of the table. If the ice melts on its own without any evaporation, the speed of rotation of the system

A man stands at the centre of turn table and the turn table is rotating with certain angular velocity. If he walks towards rim of the turn table, then

A turn table of mass M and radius R is rotating with angular velocity omega_(0) on frictionless bearing. A spider of mass m falls vertically onto the rim of the turn table and then walks in slowly towards the centre ofthe table. What is the angular velocity of the system when spider is at a distance r from the centre. Compute also the angular velocity of the turn table when the spider is at the rim and at the centre of the table .Is the energy of the system in this problem conserved ?
