A block P of weight 50 N is kept on a plane and now pulled so that the extension in the spring is 10 cm. The stiffness of the spring is 4 N/cm and the coefficient of friction between the block and the plane is μ = 0.3. Find (i) the velocity of the block as the spring returns to its undeformed state and (ii) the maximum compression in the spring.

Question
A block P of weight 50 N is kept on a plane and now pulled so that the extension in the spring is 10 cm. The stiffness of the spring is 4 N/cm and the coefficient of friction between the block and the plane is μ = 0.3. Find (i) the velocity of the block as the spring returns to its undeformed state and (ii) the maximum compression in the spring.
( By principle of conservation)
( answer= maximum compression is 2.5cm)
( explain with proper steps)
