Question 10 An object rotates with an angular speed that varies with time, as shown in the graph. How can the graph be used to determine the magnitude of the angular displacement, 0, of the object? Justify your selection. 204 15 Angular Speed (rad/s) 10 5 0- 0.0 0.5 1.0 1.5 2.0 Time (s) a. Determine the area bounded by the line and the horizontal axis from 0 s to 2 s, because 0 = 1/2wat. b. Subtract the greatest value of the angular speed from the smallest value of the angular speed because 8 = Aw. c. Determine the slope of the line from 0 s to 2 s, because the slope represents Aw/At. X d. The angular displacement cannot be determined without knowing the rotational inertia of the object
