Suppose a 1.50 kg object is suspended from the end of a silicone band. When the object is pulled down and released, the band vibrates at a frequency of 2.08 s-1. Calculate the spring constant of this silicone band including units. I know Hooke's law is F=-KX, where F is force, -K is the consent of the spring which I need to find and X is the displacement from relaxed position, but i'm giving the oscillation of the spring.
