Question

The drag force resists the motion of a car travelling at 80 km h^-1 is 300V.
(a) What power required to keep the car travelling at that speed.
(b) If the efficiency of the engine 60%, What is the power of engine?


ANSWER PLEASE CORRECTLY THE QUESTION.

Answer 1

Like friction, the drag force always opposes the motion of an object. ... for small particles moving at low speeds in a fluid, the exponent n is equal to 1.
