Let's begin with an efficiency analysis of a gasoline engine. The engine in a large truck takes in 2500 J of heat and delivers 500 J of mechanical work per cycle. The heat is obtained by burning gasoline with heat of combustion Le = 5.0 x 104 J/g. (a) What is the thermal efficiency of this engine? (b) How much heat is discarded in each cycle? (c) How much gasoline is burned during each cycle? (d) If the engine goes...

1) A motorcycle's engine delivers a top power of 12*sqrt(v), the result being in units of horsepower when the velocity is in miles/hr. Since the motorcycle's velocity isn't changing, most of this power is going toward overcoming air resistance plus a force related to squashing the tires and road (see section 10-10 of the 4th edition of Giancoli or 10-12 of the 3rd edition if you are interested). A) How much work does the engine do in 100 milliseconds at...
