How fast will the same truck move down the hill

Reference no: EM13496312

A truck can move up a road having a grade of 1.0-ft rise every 50-ft with a speed of 15 mi/h. The resisting force is equal to one twenty-fifth the weight of the truck. If its power output is the same, how fast will the same truck move down the hill? Assume that the resisting force remains unchanged.
