work hard to achieve high!
If you take the trouble to draw a sketch of the situation that you've described, the method of solution, as well as the answer, will jump out at you. The ground, the wall, and the ladder, form a right triangle. The base is 9-ft, and the hypotenuse is 15-ft. If you've been assigned this problem as homework, then you've sat through enough geometry in class to know how to work with the right triangle. The length of the missing side is 12-ft, and it makes no difference how high the wall is, as long as it's high enough to support the upper end of the ladder.
Work = 500 x 3 = 1,500 joulesPower = (work/time) = 1,500/5 = 300 watts = about 0.4 horsepower (rounded)
