Can a generous soul help me on this? A block of mass m is slid down a rough inclined plane. At the bottom of the inclined plane the block runs into another 1-kg block and comes to rest. Which expression would give the energy transferred to the second block?
assume the height of the inclined plane to be h, its length to be d and fs represent the force of friction.

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.
