Same set-up, but each string would be doubled in length by a tension $m g$ . For $l = 1$ m and $g = 9.8$ m/s², find the time to reach $B$ , in s.

Answer:

0.84

Solution:

With $k = m g / l$ all frequencies are $1/ 2$ of the earlier ones, so every time is $2$ larger: $t = \frac{2 l}{g} [\frac{π 2}{3} + sin^{- 1} \frac{1}{7}] = 0.84$ s.
