Q. A block of weight 20 kg slides with an initial velocity of 2 m sec down an inclined plane on to a spring of stiffness 10 kg/cm. If the co--efficient of friction is 0.2, angle ? = 30 the ratio of maximum compession of spring, neglecting friction to that while considering friction would be

• (A) More than one
• (B) One
• (C) Less than one
• (D) Depends on the stiffness of spring
