Solving a problem in physics, section 62, point 44 wave

44. Lying on the table body mass M = 3 kg strengthened on a horizontal spring stiffness k = 800 N / m. Bullet mass m = 10 g, flying in the direction of the spring axis with a speed υ = 500 m / s, and enters the body is stuck in it. Neglecting the mass of the spring and friction forces to determine the amplitude A and period T of oscillations of the body.
