A roller coaster (385 kg) moves from A (5.00 m above the ground) to B (27.0 m above the ground). Two nonconservative forces are present: friction does -2.00 104 J of work on the car, and a chain mechanism does +3.00 104 J of work to help the car up a long climb. What is the change in the car's kinetic energy, ?KE = KEf - KE0, from A to B? J
A Carnot engine operates between temperatures of 747 and 324 K. Calculate what the efficiency would be if (a) the temperature of the hot reservoir were raised by 42.5 K or (b) if the temperature of the cold reservoir were lowered by 42.5 K. (Give ..
