If a Mass That Is Attached to a Spring Is

question 35

Multiple Choice

If a mass that is attached to a spring is raised y ₀ feet and released with an initial vertical velocity of v ₀ ft / sec, then the subsequent position y of the mass is given by where t is time in seconds and is a positive constant. If y ₀ = 2 and = 2, find the initial velocities that result in an amplitude of 4 feet.
