A block with a mass m₁ = 9.20 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 = 0.140 m, as shown in figure (b).

A block with a mass m₁ = 9.20 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 = 0.140 m, as shown in figure (b). The two blocks are released from rest, and both start moving to the right with negligible friction. a b d k m₁ m₂ cm k m1 my m₂ m₁ 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)? m/s (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.)
