1. Put on your scientist hat and estimate how tall the fellow in the blue britches is, in the above image, if the girl in the red dress up on the clif is 3 feet tall. Also describe in whole sentences: (i) what range of heights (e.g. in feet) you were able to limit his height to, (ii) how you did the measurement (e.g. with a 1 foot plastic ruler from a print, with a program on the screen, etc.), and (iii) how you
figured out the result.
2. Much as you did with the guy, estimate the height of the clif in meters. Write just the answer below and possibly an estimate of uncertainty.
3. Using the average height value for the clif that you determined above, calculate how much time it would take a ball dropped from the height of the clif to reach bottom. Show your calculation as well as your result below.
4. Assume that the reddish dots on the picture show the position of thrown and/or dropped balls captured at equally-spaced intervals of time (like every 0.5 seconds). Using your knowledge of the fall time from the clif, estimate the size of the time interval between exposures. Briefly describe your time estimate and how you got it below.
