A block with a mass m1 = 8.10 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 m2 = 7.00 kg is pushed up against block m1, compressing the spring a distance A = 0.190 m, as shown in figure (b). The two blocks are released from rest, and both start moving to the right with negligible friction. A horizontal spring labeled k with a block labeled m1 fixed to the right end and a wall attached to the left end is shown in four configurations. The block is resting on the ground. Configuration a: The spring is relaxed and m1 is at its equilibrium position indicated by a vertical dotted line below the center of m1. Configuration b: The spring is fully compressed. Block m1 remains on the end of the spring but now a second block labeled m2 sits against the right side of m1, resting on the ground. The spring and both blocks are now to the left of the previously mentioned equilibrium position and the distance from the center of block m1 horizontally to the equilibrium position is A. Configuration c: The spring is again relaxed and m1 is at its equilibrium position. Block m2 is still against the right side of block m1 and vector v points to the right indicating the velocity of both blocks. Configuration d: The spring is stretched with block m1 on its end but now block m2 has moved to the right. The centers of the blocks are now a distace of D apart. Vector v points to the right indicating the velocity of block m2. (a) When block m1 reaches the equilibrium point, as shown in figure (c), block m2 loses contact with block m1. Block m2 continues to move right at a speed v. What is the speed v (in m/s)?
