15. The flexible belt runs around two pulleys of different radii. At the instant shown, point C on the belt has a velocity of 5m/s and an acceleration of 50m/s² in the direction indicated in the figure. Find the magnitude of the accelerations of points A and B on the belt at this instant in m/s². A R₁ = 150 mm vc, ac C R2=100 mm B
