Asked by Justin

A car travelling at 30m/s overcomes a frictional resistance of 100N while moving. Calculate the power developed by the engine.[1hp=0.75]
Answered by bobpursley`
power=force*distance/time= 100*30=3000Watts
3000watts*1hp/746watts= 4hp

the .[1hp=0.75] note you have is useless, no units. It is as silly as stating 1year=365 or 1cup=16.
