Question

A spring with spring constant 250 N/m vibrates with an amplitude of 12.0 cm when a 0.380 kg mass hangs from it. (a) What is the equation describing this motion as a function of time? Assume that the mass passes through the equilibrium point toward positive x (upward), at t = 0.110 s. (b) At what times will the spring have its maximum and minimum lengths? (c) What is the displacement at t = 0? (d) What is the force exerted by the spring at t = 0? (e) What is the maximum speed and when is it first reached after t = 0?
