2) An opening bridge takes 60 seconds to open. The opening motion is shown on the angular velocity time diagram (Figure 14). Figure 14 Angular Velocity (rad.s) 0.03 0.02 0.01 0 10 20 30 40 40 50 60 From the graph, determine: a. the maximum angular velocity b. the magnitude of the retardation c. the angle (in degrees) to which the bridge opens.
