11. A 2.0-kg piece of gelatin is made to slide down a ramp from point a to point b, as shown. The total distance between points a and b is 2.0 m while the vertical distance between the same points is 0.80 m. If the ramp is frictionless, (a) what force does work on it and (b) how much work does this force do? b.
