A car moves along a road at a constant velocity of 20 m s-1. If the resistance force acting against the car is 1000 N, what is the power developed by the engine?

Question

Harper · Answer

Answer:    power (p) = 20000watt   Explanation:     v = 20 m/s  f = 1000N      We know,   p = w/t      = (f×s) / t      = f × v      = 20 × 1000      = 20000m/s.   ans
