A Ferris wheel with radius 8.5 m initially rotates clockwise at a constant rate by completing 2.00 rev in 28.00 s. It then begins to decelerate at a rate of 0.50 rad/s2 with its only passenger at the top of the wheel. Find the direction of the total acceleration vector. Express your answer as a positive number with respect to the positive x-axis. Choose up and to the right as your positive direction.
