A spring is such that a 5-lb weight stretches it 6 in. The 5-lb weight is attached, the spring reaches equilibrium, then the weight is pulled down 3 in. below the equilib- rium point and started off with an upward velocity of 6 ft/sec. Find an equation giving the position of the weight at all subsequent times.

A spring is such that a 5-lb weight stretches it 6 in. The 5-lb weight is attached, the
spring reaches equilibrium, then the weight is pulled down 3 in. below the equilib-
rium point and started off with an upward velocity of 6 ft/sec. Find an equation
giving the position of the weight at all subsequent times.

A spring is stretched 1.5 in. by a 2-lb weight. Let the weight be pushed up 3 in. above
E and then released. Describe the motion.
