A ball \( A \) is falling vertically downwards with velocity \( v_{1} \). It strikes elastically with a wedge moving horizontally with velocity \( v_{2} \) as shown in figure. What must be the ratio \( v_{1} / v_{2} \) so that the ball bounces back in vertically upwards direction relative to wedge?https://bit.ly/YTAI_PWAP https://www.pw.live
