I have to solve this problem but every answer I've come up with so far has been wrong. If any one knows how to solve it, I'd greatly appreciate some enlightenment. Thanks. Here's the question: Two pendulums are hung adjacent to each other as shown in Fig. 7.20. Bob 1 has a mass m, and bob 2 has a mass 3m. Bob 1 is pulled aside until the support string makes an angle of 45° with the vertical direction and then is released. When the bobs collide, they stick together. What is the maximum angle made by the support strings with respect to the vertical after the collision?
