Question

When an automobile moves with constant speed down a highway, most of the
power developed by the engine is used to compensate for the energy transformations
due to friction forces exerted on the car by the air and road. If the power developed by
an engine is 176hp, estimate the total friction force acting on the car when it is
moving at a speed of 29m/s.
convert hp to watts

divide watts by speed

answer is in Newtons
