Homework Help: physics

Posted by Anonymous on Friday, February 26, 2010 at 9:43am.

A block of weight w = 35.0 N sits on a frictionless inclined plane, which makes an angle theta = 27.0 degrees with respect to the horizontal. A force of magnitude F = 15.9 N, applied parallel to the incline, is just sufficient to pull the block up the plane at constant speed. What is W_g, the work done on the block by the force of gravity w_vec as the block moves a distance L = 3.20 m up the incline?
