A sled is pulled 3 meters at constant velocity up a 20 degree incline. the efficiency of this procedure is 42%. Calculate the coefficient of friction between the crate and the incline.
alright I'm completely clueless on this one.
i know that efficiency=output (energy delivered by machine)/input (energy supplied to machine)
but i don't know what other equations I'm supposed put into play here as well.
