Barry gets impatient and leaves 5. Alison gets impatient and leaves For the last case you should not assume that you know where in the queue Alison is standing. Exercise 4: Make a plot of the function y(t) = vo Xt - 0.5 X 8 X 12 for Vo = 10,8 = 9.81, and I E [0, 2vo/8). The label on the x-axis should be time t and the label on the y-axis should be height m
