A block with a mass m, -8.50 kg is attached to a lightweight spring with a spring constant k = 100 N/m that is attached to a wall. Initially the block is at rest and the spring is relaxed, as shown in figure (a). A second block with a mass m, 7.00 kg is pushed up against block m.compressing the spring a distance A=0.160 m, as shown in figure (b). The two blocks are released from rest, and both start moving to the right with negligible friction wwwwwwwwwwwww (a) When block m, reaches the equilibrium point, as shown in figure (c), block m, loses contact with block m, Block m, continues to move right at a speed v. What is the speed vin mys)? ws (b) Block m, continues to move right, reaching the point where the spring is at the maximum stretch for the first time, as shown in Figure (d). At this point, what is the distance D between the two blocks (in cm) (Assume the widths of the blocks are much smaller than D.)
