**Jennifer**, Tuesday, December 11, 2012 at 8:47pmUsing conservation of momentum:

2*8 + 4.8*2.8 = (2+4.8)*vf = 6.8*vf

Solve for vf, the final speed of the blocks when they have the same velocity.

1/2*k*x^2 = 1/2*m*vf^2

Solve for x; k is the spring constant = 1180 N/m; x is the maximum compression of the spring
