Two shuffleboard disks of equal mass, one orange and the other green, are involved in a perfectly elastic glancing collision. The green disk is initially at rest and is struck by the orange disk moving initally to the right at V= 7.00 m/s. After the collision, the orange disk moves in a direction that makes an angle of 40.0 degrees with the horizontal axis while the green disk makes an angle of 50.0 degrees with this axis. Determine the speed of each disk after the collision.
V1 = ______m/s
V2 = ______m/s
