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 oi = 5.90 m/s as in Figure (a) shown below. After the collision, the orange disk moves in a direction that makes an angle of θ = 39.0° with the horizontal axis while the green disk makes an angle of = 51.0° with this axis as in figure (b). Determine the speed of each disk after the collision.
