Car drag racing takes place over a distance of a
mile (402 m) from a standing start.If a car (mass 1500 kg) could be propelled forward with a pulling force equal to that of gravity,what would be the change in kinetic energy and the terminal speed of the car (in mph) at the end of the race be? (For comparison,a modern,high-performance sports car may reach a terminal speed of just over 100 mph = 44.7 m/s.)
A) 604 kJ and 28.4 m/s
B) 5.92 kJ and 88.9 m/s
C) 5.92 MJ and 7900 m/s
D) 3680 kJ and 70.0 m/s
E) 5.92 MJ and 88.9 m/s
