Homework Help: Physics

Consider an ideal spring that has an unstretched length l0 = 3.3 m. Assume the spring has a constant k = 23 N/m. Suppose the spring is attached to a mass m = 6 kg that lies on a horizontal frictionless surface. The spring-mass system is compressed a distance of x0 = 1.6 m from equilibrium and then released with an initial speed v0 = 4 m/s toward the equilibrium position.


(a) What is the period of oscillation for this system?



(b) What is the position of the block as a function of time. Express your answer in terms of t.


(c) How long will it take for the mass to first return to the equilibrium position?



(d) How long will it take for the spring to first become completely extended?
