- In how many ways can you measure the height of a tall building using only
- these three tools : Stopwatch, barometer and tape measure.
- Now use your imagination. I'll give a few examples :
-
- 1. Throw the barometer out from the top of the building and use the stopwatch
- to measure the time it takes before the barometer hits the ground. The height
- h = g/2 * t^2 ............
-
- 2. Make a pendulum of the barometer and the tape measure. Lower the barometer
- until it almost touches the ground then let it swing and measure the period
- using the stopwatch. h = g * T^2 /(4*pi)^2 (I think ...)
-
- 3. While doing 2. just read out the value on the tape measure.
-
- Your turn now ...... Sven (snil@daimi.aau.dk)
