A block of mass m = 2 kg is moving with velocity v0 towards a massless unstretched spring of force constant k = 10 N/m. Coefficient of friction between the block and the ground is mu = 1/5. Find the maximum value of v0 , so that after pressing the spring the block does not return back but stops there permanently.
