20.4.5 The decision of the collection (Reshebnik) Kepe

20.4.5. Body weight m = 20 kg slides down on a smooth surface. To determine the kinetic body potential at a time when the body coordinate s = 2 m and the velocity v = 3 m / s. body potential energy n0 take zero at the position where the coordinate s = 0.
