To create this photograph, a camera shutter was opened eighteen times, producing eighteen consecutive images of
the snowboarder as he jumped. You can clearly see that there are both vertical and horizontal components to his
overall parabolic motion. To complete calculations on this sort of two-dimensional motion, it is necessary to consider
the vertical and horizontal vectors separately. By the end of this chapter, you will be able to accurately estimate the
time elapsed over the course of this image and between shutter openings, knowing only the maximum vertical height
attained by the snowboarder. You will also know how to accurately estimate his maximum vertical height using only
the time he spent in the air.
