Solve the all parts of given question:
Question: A 1325-kg car coasts in neutral down a 2.11° hill. The car attains a terminal speed of 21.0 m/s.
Part A: How much power must the engine deliver to drive the car on a level road at 21.0 m/s?
Part B: If the maximum useful power that can be delivered by the engine is 42.0 kW, what is the steepest hill the car can climb at 21.0 m/s?
I need help to find how much power the engine must deliver to drive the car on a level road.
