The upper ball shown in the figure to the right is released from rest, collides with the stationary lower ball, and sticks to it. The strings are both 80.0 cm long. The upper ball has a mass of 2.00 kg, and is pulled to the right such that the string makes an angle θo = 25.0o to the vertical. The lower ball has a mass of 1.50 kg. Find the frequency and maximum height of the motion following the collision.
