A circular disc of mass \( 2 m \) and radius \( 3 r \) is resting on a flat frictionless surface. Another circular disc of mass \( m \) and radius \( 2 r \) , moving with a velocity \( u \) hits the first disc as shown in the figure. The collision is elastic.https://bit.ly/YTAI_PWAP https://www.pw.live
