Suppose a 32-pound weight stretches a spring 2 feet. If the weight is released from rest
Chapter 7, Problem 71(choose chapter or problem)
Suppose a 32-pound weight stretches a spring 2 feet. If the weight is released from rest at the equilibrium position, find the equation of motion x(t) if an impressed force f(t) 20t acts on the system for 0 t 5 and is then removed (see Example 5). Ignore any damping forces. Use a graphing utility to graph x(t) on the interval [0, 10].
