An iron ball A collides with another stationary iron ball B If the ratio of radii of the balls is n = 2, find the ratio of their speeds just after the collision (e = 0.5)

Explanation

Directly from the derived result (general formula)
`v_(1)=(m_(1)-em_(2))/(m_(1)+m_(2))("since " u_(2)=0)` and `v_(2)=(m_(1)(1+e))/(m_(1)+m_(2))("since " u_(2)=0)`.
