A disk moving on a frictionless horizontal table collides elastically y with another identical disk as shown. The directions of motion of the two disks make angles 0 and ϕ with the initial line of motion as shown. Then

Two identical balls A and B lie on a smooth horizontal surface which then takes up the curved path. What is the minimum coefficient of restitution
