please help.. i really need the answer as soon as possible..

Two shuffleboard disks of equal mass, one orange and the other yellow are involved in a

perfectly elastic glancing collision. The yellow disk is initially at rest and is struck by the

orange disk moving initially to the right at 7.00 ms"1. After the collision, the orange disk

moves in a direction that makes an angle of 39°.with its initial direction. Meanwhile, the

velocity vector of the yellow disk is perpendicular to the post collision velocity vector of the

orange disk.

a) Determine the speed of each disk after the collision.
