PASSAGE
A 4 kg block sits on a horizontal surface (μs=0.4\mu_s = 0.4, μk=0.3\mu_k = 0.3). A spring (k=500 N/mk = 500 \text{ N/m}) is attached horizontally to the block at one end and to a wall at the other. The block is displaced x1=0.06 mx_1 = 0.06 \text{ m} from the spring's natural length position (stretching the spring) and released from rest. Take g=9.81 m/s2g = 9.81 \text{ m/s}^2.
Immediately after release, the block does not move. What is the minimum spring displacement xminx_{min} at which the block would just begin to slide, and does the block eventually come to rest at the spring's natural length position after one or more oscillations?
