Question

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.
