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 initially to the right at varrowboldoi = 4.70 m/s as in Figure
(a) shown below. After the collision, the orange disk moves in a direction that makes an angle of ? = 40.0° with the horizontal axis while the green disk makes an angle of phi = 50.0° with this axis as in figure
(b). Determine the speed of each disk after the collision.
