A horizontal block-spring system with the block on a frictionless surface has total mechanical energy E = 46.9 J and maximum displacement from equilibrium of 0.227 m. (a) What is the spring constant? 1820.3 N/m (b) What is the kinetic energy of the system at the equilibrium point? 46.9 J (c) If the maximum speed of the block is 3.45 m/s, what is its mass? 7.88 kg (d) What is the speed of the block when its displacement is 0.160 m? m/s (e) Find the kinetic energy of the block at x = 0.160 m. (f) Find the potential energy stored in the spring when x = 0.160 m. (g) Suppose the same system is released from rest at x = 0.227 m on a rough surface so that it loses 12.1 J by the time it reaches its first turning point (after passing equilibrium at x = 0). What is its position at that instant?
