The time of a pendulum varies as the square root of its length. If the length of a pendulum which beats 15 seconds is 9 cm, find: a) The length that beats 80 seconds. b) The time of a pendulum with length 36 cm.
Added by Michael O.
Step 1
We know that the time of a pendulum varies as the square root of its length. We can represent this relationship as: T = k * √L where T is the time, L is the length, and k is a constant of proportionality. Show more…

Period of a pendulum The period $P$ of a simple pendulum that is, the time required for one complete oscillation - is directly proportional to the square root of its length $l$. (a) Express $P$ in terms of $l$ and a constant of proportionality $k$ (b) If a pendulum 2 feet long has a period of 1.5 seconds, find the value of $k$ in part (a). (c) Find the period of a pendulum 6 feet long.

Period of a Pendulum The period $T$ (in seconds) of a simple pendulum as a function of its length $l$ (in feet) is given by $T(l)=2 \pi \sqrt{\frac{l}{32.2}}$ (a) Express the length $l$ as a function of the period $T$ (b) How long is a pendulum whose period is 3 seconds?
