A merry-go-round rotates at the rate of 0.15 rad/s with a(n) 91.9 kg man standing at a point 2.6 m from the axis of rotation. What is the new angular speed when the man walks to a point 1.9 m from the center? Assume that the merry-go-round is a solid 1.51×102 kg cylinder with a radius of 3.88 m. Answer in units of rad/s.

Asteam power plant operates on an ideal reheat rankine cycle between the pressure limits of 15 mpa and 10 kpa. the mass flow rate of steam through the cycle is 12 kg/s. steam enters both stages of the turbine at 500°c. if the moisture content of the steam at the exit of the low-pressure turbine is not to exceed 10 percent, determine (a) the pressure at which reheating takes place, (b) the total rate of heat input in the boiler, and (c) the thermal efficiency of the cycle. also, show the cycle on a t-s diagram with respect to the saturation lines.
