And I realize now that this is also because the linear deceleration assumption doesn't match the average deceleration stated in the problem. It actually decelerates faster and cuts under the t=1s and t=2s points in the velocity graph, and therefore is actually a slightly larger underestimate. -- https://mail.python.org/mailman/listinfo/python-list
