5) A horizontal plywood disk with mass 8.00 kg and radius 0.600 m pivots on a frictionless bearing about a vertical axis through its center. A circular model railroad track of negligible mass and radius 0.500 m is attached to the disk. A 1.20 kg battery driven model train rests on the tracks. The train begins from rest and rapidly attains a constant speed of 0.550 m/s relative to the tracks. Find the magnitude and direction of the angular velocity of the disk relative to the earth.
