In the system below, the block has mass M = 2.0 kg, the spring has constant k = 500 N/m, and this spring-mass system is at rest. A projectile of mass m = 10g, with a speed of 800 m/s, collides with the block and becomes lodged inside. There is friction between the block and the floor on which it rests. a) What is the initial amplitude of the oscillation that the system acquires, right after the shock? Note: Assume the effect of friction on a single swing is negligible. b) Knowing that the amplitude is halved in 20 seconds, calculate the damping factor due to friction? c) How many oscillations, approximately, occurred in these 20 seconds?
