Question

An automobile uses 100 hp and moves at a uniform speed of 60m/s. What is the forward thrust exerted by the engine on the car?

Answer 1

we know,
1 HP = 746 watt

so, power = 100HP = 74600 watt

power = force x velocity

74600 =force x 60

force = 74600/60 = 7460/6 N
= 1243.33 N
hence,

upthurst exerted by the engine on the car = 1243.33 N
