A block of mass 0.25 kg is against a spring compressed at 0.20 m with spring constant 50 N/m. When the spring is released, the block moves along the frictionless surface until entering a region with the coefficient of kinetic friction equal to 0.30 (when the block enters the friction region it is no longer in contact with the spring ). How far,L,into the region with friction does the block slide before stopping?
