A block of mass 0.85 kg is pressed against a horizontal spring with a spring constant of 320 N/m. The surface is horizontal and frictionless except for a patch of length 28.3 cm over which the coefficient of kinetic friction between it and the block is 0.428. If the spring is compressed 13.7 cm before the block is released, what is the speed of the block after it passes through the patch with friction? answer in m/s
