The figure shows a pendulum set up composed of mass A (100 g) and mass B (300 g). Mass A is pulled to the left until its height is 5 cm relative to its original position. After being released, it collides with mass B. Find the maximum angular displacement of mass B, α. Assume collision as central impact with coefficient of restitution of 0.75. State your answer in degrees.
