45. "The drawing shows a device that you can make with a piece of cardboard, which can be used to measure a person's reaction time. Hold the card at the top and suddenly drop it. Ask a friend to try HOLD HERE -180 ms- d3 -120 ms- d2 60.0 ms- ******* to catch the card between his or her thumb and index finger. Initially, your friend's fingers must be level with the asterisks at the bottom. By noting where your friend catches the card, you can determine his or her reaction time in milliseconds (111s). Calculate the distances di, d, and dz.
