A force of 50 pounds exerted at an angle of 25 degree with t

A force of 50 pounds, exerted at an angle of 25 degree with the horizontal, is required to slide a desk across a floor. Determine the work done in sliding the desk 15 feet.

force = 50 pounds

angle = 30 degrees

work done is given by

W = F.D

||F|| || D || cos theta

W = 50* 15 * cos 25

therefore work done is

W = 679.73
