an engine expends 40.0 hp in propelling a car along a level trackata constant speed of 15.0m/s. How large is the totalretarding forceacting on the car? (book answer 1.99kn)
power (p) = 40.0 hp
speed (v) = 15.0 m/s
force = power/speed
f=29828/15 = 1988.5 = 1.99
40hp x 745.7w = 29828 w
why did I have to convert the 40hp to watts
im trying to understand this physics, but am having a hardtime. Iknow there is an explanation out there, that willmake it allclick. any help is appreciated. thanks
