a kg block is held at rest against a spring with a force constant k = N/m. Initially, the spring is compressed a distance d. When the block is released, it slides across a surface that is frictionless, except for a rough patch of width cm that has a coefficient of kinetic friction µk =. Find d such that the block's speed after crossing the rough patch is m/s.
