Question

A student pulls a (34) kg box a distance of (13.50) m up a ramp set at 25.8o using a force of (181) N applied parallel to the ramp. Find the efficiency of the ramp. Give your answer in percent (%) and with 3 significant figures.

Answer 1

work done=34*9.8*13.5*sin25.8
work applied=181*13.5

efficiency=workdone/workapplied *100
