Mr. Doyle is pulling his friend up a 25.0° hill in a sled. He is pulling with a force of 676 N at an angle of 30.0° to the incline. The sled starts from rest and has an acceleration of 1.24m/s^2. If the normal force is 328.8 N, what is the mass of the sled? What is the coefficient of friction between the sled and the snow? How fast is the sled moving at the top of a 25.0 m hill? How long does it take Mr. Doyle to transport his passenger to the top of the hill?

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.
