Two Bals. of masses
mA = 45 grams and mB = 65 grams
are suspended as shown. The lighter ball is pulled away to a 66 degree angle with the vertical and released:
=============================
---------/| | -
--------/è| | |
-------/ | | | 30 cm
------/ | | |
-----mA | | |
----------mA mB -
where è = 66 degrees, and the height that they are suspended at is 30 cm.
a) What is the velocity of the lighter ball before impact?
b) What is the velocity of each ball after the elastic collision?
c) What will be the maximum height of each ball after the elastic collision?
======================================
I can break up the problem into 3 parts
First : Conservation of Energy
Second: Elastic Collision
Third : Conservation of Energy for each mass.
EDIT: FIXED FORMATTING.

Two Balls of masses
mA = 45 grams and mB = 65 grams
are suspended as follows: both Balls are hanging by a 30 cm string and are vertically parallel to each other. The lighter ball is pulled away to a 66 degree angle with the vertical and is released, hitting the larger mass.
