Question
The figure below shows a simple device for measuring your reaction time. It consists of a cardboard strip marked with a scale and two large dots. A friend holds the strip vertically, with thumb and forefinger at the dot on the right in the figure below. You then position your thumb and forefinger at the other dot (on the left in the figure), being careful not to touch the strip. Your friend releases the strip, and you try to pinch it as soon as possible after you see it begin to fall. The mark at the place where you pinch the strip gives your reaction time.

Your friend releases the strip, and you try to pinch it as soon as possible after you see it begin to fall. The mark at the place where you pinch the strip gives your reaction time. How far from the lower dot should you place the 50.0 ms mark?Explanation / Answer
Apply d = vot + .5at^2
d = (0) + (.5)(9.8)(50 X 10^-3)^2
d = .01225 m
That is 1.225 cm away
