Asked by Olivia

a car is moving at a constant speed of 20m/s^-1. The force retarding its motion is 500N. Calculate the engine power of the car required to maintain the motion
Answered by Nam
The net force must be 0 in order to maintain the motion according to Newton's first law of motion.
=> F=500N
Engine power P = F.x/t = F.v = 10000J/s
