Question

A ball with initial speed of10m/s collides elastically with two other identical balls at rest as shown in figure, whose centres are on a line perpendicular to the initial velocity and which are initially in contact with each other.All the three balls are lying on a smooth horizontal table. The first ball is aimed directly at the contact point of the other two balls.All the balls are smooth. Find the velocities of the three balls after the collision.

Answer 1

Correct Answer - `[2m//s,6.93 m//s" ""at"" "30^(@)"with incident direction"]`
