A spring of unstretched length L and spring constant k is attached to a wall and an object of mass M resting on a k frictionless surface (see figure). The object is pulled such that the spring is stretched a distance A then released. Let the +x- direction be to the right. What is the position function x (t) for the object? Take x = 0 to be the position of the object when the spring is relaxed, and make the phase angle as simple as possible. 1) = 4. What is the velocity v, of the object at t =T, where T is the period? Write the expression using fractions, not decimal values. What is the acceleration a, of the object at t3= ax =
