A sleigh and driver with a total mass of 130 kg are pulled up a hill with a 15 degree incline by a horse
If the overall retarding frictional force is 800 N and the sled moves up the hill with a constant velocity of 5.0 km/h,
what is the power output of the horse? (Express in horsepower, of course.)
The Attempt at a Solution
I first converted the 5 km/h to m/s
5km/h = 1.389 m/s
Not sure what to do now. I know there is a retarding force of 800N and i know the velocity so i want to say i can find the force by the horse to travel at that velocity with that retarding force but im not sure how. cause then i believe if that force is found i could multiply that by the velocity to get the power in watts then convert to horsepower.
thanks for any help :)
