A block of mass M₁=11.8 kg and initial velocity v₀=4.70 m/s collides with a block of mass M₂=4.80 kg and initial velocity of −4.70 m/s. Attached to M₂ is a spring with a force constant k=1.40×10⁴ N/m. At one point the velocities of block M₁ and block M₂ are equal. You can ignore friction in this problem.

6a. What is the speed (in m/s) of block M₁ at that point?

6b. What is the compression of the spring (in meters) when the velocities of the blocks are equal?
