Задача id13301

A spring of stiffness k is attached to a stationary cart of mass M, which is in a compressed state, in contact with a stationary load of mass m (figure). The spring is compressed to a distance x0 from the equilibrium position, and the distance from the load to the right open edge of the cart is L, the length of the spring in the uncompressed state is less than L. The spring is released, and it pushes the load off the cart. What will be the speed v of the load when it slides off the cart? The coefficient of friction of the load on the trolley is equal to a, the friction of the trolley on p
