A block of mass 20 kg on a horizontal surface where uk = 0.4is pushed against an initially relaxed spring that has a force constant k = 100 N/m, compressing it 1.50 meters. It is then released, what is the maximum velocity of the mass? Hint the maximum velocity occurs before the relaxed spring equilibrium point.

A 2.70 kg mass is pushed against a horizontal spring of force constant 28.0 N/cm on a frictionless air table. The spring is attached to the tabletop, and the mass is not attached to the spring in any way. When the spring has been compressed enough to store 10.0 J of potential energy in it, the mass is suddenly released from rest. What is the greatest acceleration of the mass? Express your answer with the appropriate units.
