4. Assume that ball A of weight W is released from rest in theposition ?ଵ ൌ 60° and swings downward to where it strikes theat-rest ball B of weight 3W . Assuming an elastic impact,calculate
(a) the angle ?ଶ through which the lager pendulum (Pendulum B)will swing after the impact.
(b) The total energy loss just after impact The length of therods for both pendulum A and B are equal to ?.
You may assume W =196.2 N and ? = 1 m for numericalcalculations.
