Please answer questions 3, 4 and 5!A 780 g object is hung from a spring with a force constant of 30 N/m. What is the displacement of the spring from equilibrium length if it is hanging verticallyNow, the mass in question a is being pulled downward by an additional 9 cm. What is the potential energy?You release the object, what is the period of oscillation of the mass/spring system? Using yt=Acos(wt), what is the expression of the vertical motion along the y-axis? What is the maximum speed of the oscillating object? What is the maximum kinetic energy? Do these values make sense from the values in part b?
