Question 1
The engine of a 3500-N car is generating a constant power of 50 hp (horsepower)
while the car is traveling up the slope with a constant speed. If the engine is
operating with an efficiency of € 0.8, determine the speed of the car. Neglect
drag and rolling resistance. Use g 9.81 m/s² and 1 hp = 745.7 W.
