A spring with spring constant 230 N/m vibrates with an amplitude of 12.0 cm when 0.530 kg hangs from it. (a) What is the equation describing this motion as a function of time? Assume the mass passes through the equilibrium point, toward positive x (upward), at t = 0.120 s. The equation is: http://www.webassign.net/symImages/c/b/444b09c7ddeb5c844763b063d17f67.png (b) At what times will the spring have its maximum and minimum lengths? (Consider only the first instances after t = 0.) (c) What is the displacement and direction at t = 0? (d) What is the force and its direction exerted by the spring at t = 0? (e) What is the maximum speed? When is it first reached after t = 0?
