A 650KW power engine of a vehicle of mass 1.5∗105kg is rising on an inclined plane of inclination 1 in 100 with a constant speed of 60km/hr. Find the frictional force between the wheels of the vehicle and the plane.
Given,
Power of engine (P)=650kw=650000W
Mass of vehicle m=1.5∗105kg
Inclination Sinθ=1100
Speed of vehicle (v)=60km/hr=60∗100060∗60=503m/s
Frictional force (fr)=?
We have, total upwarding force F=fr+mgsinθ ⇒ Pv=fr+mgsinθ
