Body 1 with a mass of 60 kg moves with velocity v = 1 m / s. The moment of inertia of a cylinder of radius r = 0.2 m relative to the axis of rotation IA = 2 kg • m2 Determine the kinetic potential of the system when the body 1 is at a height y = 1 m if the potential energy of the system is zero for y = 0.
