Two shuffleboard disks of identical 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 4.90 m/s. After the collision, the orange disk moves in a direction that creates an angle of 39.8 degree with its initial direction. Meanwhile, the velocity vector of the yellow disk is perpendicular to the post collision velocity vector of the orange disk. Evaluate the speed of each disk after the collision.
