14 - Masses m1=1kg and m2=2kg are connected to each other by a light rope passing through a frictionless pulley. While mass m1 is connected to a spring with constant k=100 N/m in the horizontal plane with a friction coefficient of µ=0.4, mass m2 hangs freely. It is released when the spring is at its normal length. Calculate the distance h that the m2 mass will descend the most.
