A38.2 kg wagon is towed up a hill inclined at 17.5 ◦ with respect to the horizontal. the tow rope is parallel to the incline and has a tension of 129 n in it. assume that the wagon starts from rest at the bottom of the hill, and neglect friction. the acceleration of gravity is 9.8 m/s 2 . how fast is the wagon going after moving 85.4 m up the hill

Acoal-fired plant generates 600 mw of electric power. the plant uses 4.8 x 10^6 kg of coal each day, and the heat of combustion of coal is 3.3x 10^7 j/kg. the steam that drives the turbines is at a temperature of 300° c, and the exhaust water is at 37° c. (a) what is the overall efficiency of the plant for generating electric power? (b) how much thermal energy is exhausted each day? (c) what is the change in entropy of the universe for this heat engine? (d) using the same heat reservoirs, what is the maximum possible (carnot) efficiency for a heat engine?
