Collision Between Two Balls
Two identical steel balls, each of mass 4.0 kg, are suspended from strings of length 39 cm so that they touch when in their equilibrium position. We pull one of the balls back until its string makes an angle theta = 29° with the vertical and let it go. It collides elastically with the other ball.
How high will the other ball rise?
4.89 cm
Suppose that instead of steel balls we use putty balls. They will collide in elastically and remain stuck together after the collision. How high will the balls rise after the collision?
1.222 cm

This was the most helpful for me for part 2, though they do
explain part 1 as well. Just scroll down to question 2.
