A horizontal spring with force constant k-635 N/m is attached to a wall at one end and to a block of mass m-2.50 kg at the other end that rests on a horizontal surface. The block is released from rest from a position 3.40 cm beyond the spring's equilibrium position, (a) If the surface is frictionless, what is the speed of the block as it passes through the equilibrium position? (b) If the surface is rough and the coefficient of kinetic friction between the box and the surface is 0.200, what is the speed of the block as it passes through the equilibrium position?
