Have a friend hold a ruler by one end, letting the other end hangdown vertically. At the lower end, hold your thumb and index fingeron either side of the ruler, ready to grip it. Have your friendrelease the ruler without warning. Catch it as quickly as youcan.
If you catch the ruler 8.7 cm from the lower end, what is yourreaction time?
I have tried this (unsuccessfully) and would like help.
