In the picture below, block 1 slides on frictionless ice towards block 2. Block 2 initially sits against a spring, at the spring's equilibrium position. The two blocks collide (do NOT assume the collision is either elastic or perfectly inelastic), and subsequently, block 2 compresses the spring a total distance of x; before stopping. As block 2 slides to the right, it experiences kinetic friction. The values of various constants are: m1 = 4.0 kg, m; = 9.0 kg, \"mama: = '7 mfs, If = 0.4-5 m, pk = 0.40, k = 350 me |:> Moment A: Some time before collision: Moment D: where block 2 has come to rest and the spring is compressed a distance xf: 3. There are four key moments in time that occur in this setup, including the two shown above. In words, describe precisely what is happening at moments B and C, which occur between the two moments shown above. b. Find the velocity of block 2 immediately after the collision.
