Ablock of mass m slids up a ramp making an angle θ with the horizontal. the block has an initial ke of 1 2 m v2 0 as it starts up the ramp and travels a distance l along the ramp before coming to momentary rest. v0 l how much work did kinetic friction do on the block between its starting point and the point it came to momentary rest?

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%)
