1.Two shuffle board disks of equal mass, one orange and the other yellow are involved in an elastic, glancing collision. The yellow disk is initially at rest and is struck by the orange disk moving with a speed of 4m/s. After the collision, the orange disk moves along a direction that makes an angle of 73° with its initial direction motion. The velocities of the two disks are perpendicular after the collision. Determine the final speed of each disk.
