A thin light plate is affixed on the upper end of a spring of force constant k, lower end of which is affixed on the ground. An inverted beaker of mass M is placed on the plate. A putty blob of mass m is stuck inside the beaker at its bottom as shown in the figure. After some time, when the adhesion of the putty become too weak to support it, the putty blob falls. The putty hits the plate after the plate has completed exactly one oscillation and sticks there. If the beaker does not lose contact with the plate, find height h of beaker and amplitude A of the oscillations of the system after the putty sticks to the plate. Acceleration of free fall is g.
