3. The 2kg ball is attached to 1.2 m light string, making a simple pendulum. It is displaced angle 45 degrees from the vertical and released at t=0s. Directly below the pivot of the pendulum is a 2kg box, attached to a spring of constant k=0.4N/m on a frictionless, horizontal surface. When the boll collides with a box, the boll disconnects from the string and sticks to the box. (a) At what time will the spring first reach its maximum compression? (b) Find the amplitude of the spring oscillations. α
