Amal, a physics student suggested a way to measure the total change in internal energy during one entire bounce. 1. Amal's idea is to use the end of the first bounce, when the puck momentarily stops near the top of the ramp. Use Amal's method to find the total decrease in mechanical energy of the system during one complete bounce. Describe your process and results in the space below.

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. (2.15 mpa; 45.0 mw; 42.6%)
