A child of mass 53.7 kg sits on the edge of a merry-go-round with radius 2.2 m and mo- ment of inertia 205.327 kgm2. The merry- go-round rotates with an angular velocity of 1.6 rad/s. The child then walks towards the center of the merry-go-round and stops at a distance 0.836 m from the center. Now what is the angular velocity of the merry-go-round? Answer in units of rad/s.

Arigid tank is divided into two equal parts by a partition. one part of the tank contains 3 kg of compressed liquid water at 400 kpa and 60°c while the other part is evacuated. the partition is now removed, and the water expands to fill the entire tank. determine the entropy change of water during this process, if the final pressure in the tank is 40 kpa. use steam tables.
