On the edge of a massive cart (figure) resting on a horizontal plane, there is a cylindrical vessel of radius r and height H, in the lower part of which there is a small hole with a stopper. The vessel is filled with liquid of density p. At time t = 0, the plug is removed. Find the maximum speed that the cart acquires, assuming that H > r and M > pr2pН, where M is the mass of the cart with the vessel. Explain the meaning of these restrictions. Friction in bogie bearings, rolling friction and internal fluid friction
