A 3.2-kg object is suspended from a spring with k = 74 N/m.  The mass is pulled 0.75 m downward from its equilibrium position and allowed to oscillate.  What is the maximum kinetic energy of the object

An ideal spring hangs from the ceiling. A 1.75 kg mass is hung from the spring, stretching the spring a distance d=0.0865 m from its original length when it reaches equilibrium. The mass is then lifted up a distance L=0.0295 m from the equilibrium position and released. What is the kinetic energy of the mass at the instant it passes back through the equilibrium position?

A horizontal block-spring system with the block on a frictionless surface has total mechanical energy E = 46.9 J and a 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. J (f) Find the potential energy stored in the spring when x = 0.160 m. J (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? m

A 0.500-kg object, suspended from an ideal spring of spring constant 21.4 N/m, is oscillating vertically. How much change of kinetic energy occurs while the object moves from the equilibrium position to a point 4.73 cm lower?
