On a smooth horizontal surface is a wooden box with sand mass M = 50 kg. It misses bullet mass m = 10 g, flying horizontally at V0 = 800 m / s, and is stuck in it. Find the maximum deformation of the spring, holding the box if its stiffness k = 1 kN / m.

Detailed solution shorthand terms, formulas, laws used in the decision, the withdrawal of the calculation formula and the response.
