8. A block of mass m is placed on a bar of mass M, which rests on a frictionless horizontal floor. The floor terminates into a wall where an ideal spring is attached as shown in the figure. When the spring is compressed by an amount 1, all inter-turn spacing of the spring vanishes. Coefficient of friction between the bar and the block is u. If the bar is pushed towards the wall so that it strikes the spring with a velocity u, what should be range of spring constant so that the block does not slide relative to the bar?
