This assembly is made with mass less strings attached to balls. Ball A (m = 0.3kilogram) is released from height 0.2 meter above Ball B (m = 0.5kilogram) also at rest. The two undergo an elastic collision. Find what max height does each ball achieve after collision? The picture shows a brick wall with Ball A going up in southwest direction and Ball B is at rest from brick wall hanging 0.2 meter.
