Chapter 7, Problem 69(choose chapter or problem)
If a mass that is attached to a spring is raised feet and released with an initial vertical velocity of , then the subsequent position y of the mass is given by where t is time in seconds and is a positive constant. (a) If , ft, and , express y in the form , and find the amplitude and period of the resulting motion. (b) Determine the times when that is, the times when the mass passes through the equilibrium position.
