If an undamped spring-mass system with a mass that weighs 24 lb and a spring constant 9 lbin is suddenly set in motion at t=0 by an external force of 288cos(4t) lb, determine the position of the mass at any time. Assume that g=32 fts2. Solve for u in feet.
Enclose arguments of functions in parentheses. For example, sin(2x).
