7. Suppose that you are driving along at a steady 25 m/s (nearly 55 mph). Draw the v ys t graph on the axes below. At time t = 2.0 s, you look down at your cell phone, without changing speed.
At time t = 5.0 s, you return your attention to the road. On the graph below represent the distance you
traveled, while you weren't really paying attention to your driving. What is this distance?

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?
