A car is travelling up the inclined plane with an inclination of 14^{o} with a velocity of v = 50 Km/h. The mass of the car is 4 Mg. If mechanical friction and wind resistance are neglected, determine the power developed by the engine if the automobile has an efficiency E = 0.5 1) 263.7 kW 

Equation of motion:
The force F which is required to maintain the car's constant speed up
the slope must be determined first: Power: Here, the speed
of the car is The power output can
be obtained as: The required power
inout to the engine to provide the above power output is So the power developed
by the engine with an efficiency E(0.5) is 263.7 kW
