Bad photography and good calculus

Featured on BIMMERPOST.com

Just in case you are in the mood for bad photography and good calculus here goes. Take a look at the photo, and you’ll see that the focus is pretty decent, but there’s a lot of blur caused by the motion of the car. Look again, and you’ll see that there 16 chalk marks around the tire. Check out the chalk mark touching the road, and you will see that there is no blur at all.

This is the calculus fact: Points on the wheel are constantly changing speed, relative to a fixed point, as you drive along. The point on the tire above the axle is moving at twice the speed of the car, while the point below the axle has instantaneous speed 0 (assuming you aren’t spinning your wheels).
