wo sticky spheres are suspended from light ropes of length l that are attached to the ceiling at a common point. sphere a has mass 2m and is hanging at rest with its rope vertical. sphere b has mass m and is held so that its rope makes an angle with the vertical that puts b a vertical height h above a. sphere b is released from rest and swings down, collides with sphere a, and sticks to it. in terms of h, what is the maximum height above the original position of a reached by the combined spheres after their collision?
