Question: You push a block (m= 200 g) against a horizontal spring (k = 200 N/m), compressing the spring a distance d = 15 cm.

You push a block (m= 200 g) against a horizontal spring (k

You push a block (m= 200 g) against a horizontal spring (k = 200 N/m), compressing the spring a distance d = 15 cm. The block is on a frictionless surface. Beyond the equilibrium position of the uncompressed spring is a rough surface (L = 60 cm) that has a coefficient of friction uk. Following this surface is a frictionless curved ramp. LOOD d = 15 cm L = 60 cm h (a) The block rises to a height H = 0.95 meters up the curved ramp. How much mechanical energy is "lost"? Where did it go? (b) Calculate the velocity of the block just after it loses contact with the spring, and just after it crosses the rough surface? (c) Find the coefficient of kinetic friction, uk.
