A compact car travelling at `27 m//s` on a level highway experiences a frictional force of 300 N due to air resistance and the friction of types with the road. What is the horse power of the engine of the car ?

Text Solution

Verified by Experts

As `upsilon = 27m//s, F = 300 N, P= Fupsilon = (300N) (27m//s)`
`=8100 J//s = 8100 W = (8100W)/((746 W)//hp) ~~ 11hp.`
