physics

A block of weight w = 25.0 N sits on a frictionless inclined plane, which makes an angle = 25.0 with respect to the horizontal, as shown in the figure. A force of magnitude F= 10.6 N , applied parallel to the incline, is just sufficient to pull the block up the plane at constant speed.

The block moves up an incline with constant speed. What is the total work done on the block by all forces as the block moves a distance L= 2.60m up the incline? Include only the work done after the block has started moving at constant speed, not the work needed to start the block moving from rest.
What is , the work done on the block by the force of gravity w as the block moves a distance
L= 2.60m up the incline?
