Question 14 Net Force (N) Time is A net force is applied to the edge of a disk that has a diameter of 0.5 m. The disk is initially at rest. A graph of the net force as a function of time for the edge of the disk is shown. The net force is applied tangent to the edge of the disk. How can a student use the graph to determine the change in angular momentum of the disk after 8 s? Justify your selection Determine the vertical intercept, multiply the result by 0.25 m, and then multiply that result by 8 s. This procedure can be used because AL = TAt with T=rF. Determine the slope of the curve of the graph from 0 s to 8 s, multiply the result by 0.25 m, and then multiply that result by 8 s. This procedure can be used because AL = TAt with T = rf.

Determine the slope of the curve of the graph from 0 s to 8 s, multiply the result by 0.50 m, and then multiply that result by 8 s. This procedure can be used because AL = TAt with T=TF. Determine the area bound by the curve and the horizontal axis 0 s to 8 s, multiply the result by 0.50 m, and then multiply that result by 8 s. This procedure can be used because AL = TAt with T = F.
