Ablock of mass m = 0.600 kg is pressed against a horizontal spring of elastic constant k = 20 n/m, compressing it by 20.0 cm. the block is then released. once it loses contact with the spring, the block travels a distance 33 cm on a rough horizontal surface before it comes to a stop. what is the coefficient of kinetic friction between the block and the surface?
