C2M.1 Figure C2.10 shows a time-lapse photograph of another collision between two floating disks. In this case, the two disks have the same mass. Make a photocopy of this diagram (or scan and print it) and then construct arrows that show that the fourth principle of mechanics is consistent with this photo. Carefully compare both the magnitude and direction of the impulses delivered to each disk by the collision. [Hints: Create a magnified image if you can. Draw arrows from pentagon center to pentagon center (you can skip one or two intervening images to get bigger arrows). Use images just before and just after the collision, but do not use the image where the disks touch. ]
