In the figure (Figure 1) the upper ball is released from rest, collides with the stationary lower ball, and sticks to it. The strings are both 48.0 long. The upper ball has mass is 1.80 and it is initially 10.0 higher than the lower ball, which has mass 3.15 what's the frequency of the motion after the collision? what's the maximum angular displacement of the motion after the collision?
