Question
![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 voi = 6.05 m/s as in Figure a, shown below. After the collision, the orange disk moves in a direction that makes an angle of 8 = 38.0° with the
horizontal axis while the green disk makes an angle of = 52.0° with this axis as in Figure b. Determine the speed of each disk after the collision.
