A semi-truck of mass 25,000 lb (1 kg = 2.2 lb) enters a highway ramp at 10 mph (1 m/h = 0.447 m/s). It accelerates to 75 mph while merging with the highway at the end of the ramp at an elevation of 15 m.
(a) Determine the change in mechanical energy of the truck.
(b) If the heating value of diesel is 40 MJ/kg and the truck engine is 30% efficient (in converting heat to mechanical energy), determine the mass of diesel (in kg) burned on the ramp.
