A race track is constructed such that two arcs of radius 80 m at A and 40 m at B are joined by two stretches of straight tracks as in the figure. In a particular trial run, a driver traveled at a constant speed of 50 m/s for one complete lap. In this case, the ratio of the tangential acceleration at A to that at B is

A heat engine absorbs 2 500 J of heat from a hot reservoir and expels 1 000 J to a cold reservoir. When it is run in reverse, with the same reservoirs, the engine pumps 2 500 J of heat to the hot reservoir, requiring 1 500 J of work to do so. Find the ratio of the work done by the heat engine to the work done by the pump. Is the heat engine reversible?

a. 1.0 (no) b. 1.0 (yes) c. 1.5 (yes) d. 1.5 (no) e. 2.5 (no)
