Q. Two identical balls A and B of equal masses are lying on a smooth horizontal surface as shown in the fig. Ball A hits ball B with a velocity 16 ms−1. What should be the minimum value of coefficient of restitution ′e′ between A and B so that B just reaches the highest point of the inclined plane? Take g=10 ms−2.
