A 4kg block is pushed up an inclined that makes a 30 degree angle with the horizontal as shown in the figure. Once the block is pushed a distance of d=5.0m up the incline, the block remains at rest. What is the approximate change in the gravitational potent ion energy of the block-Earth system when the block is held at rest compared to its original location at the bottom of the incline?
