A mass m, which is attached to a spring with spring constant k, oscillates on a horizontal table, with amplitude A. At an instant when the spring is streched by sqrt(3) A//2, a second mass m is dropped vertically onto the original mass and immediately sticks to it. what is the amplitude of the resulting motion-
