What is the approximate length of a pendulum that takes 2.4 pi seconds to swing back and forth?
1 answer:
Answer:
The approximate length of the pendulum is 46.08 ft
Step-by-step explanation:
The time (t) of pendulum oscillation is given as;
where;
L is the length of the pendulum
g is acceleration due to gravity = 9.8 m/s² = 32.15 ft/s²
t is the time given as 2.4 π seconds
From the equation above, make L the subject of the formula;
Therefore, the approximate length of the pendulum is 46.29 ft
The closest option is 46.08 ft

Step-by-step explanation:
Hihi. So, this is a nice application of interest rates as well as properties of exponentials/logarithms. As you know, the basic equation for interest rates is A= Pe^(rt) where A is your final amount, P is your initial, r is your rate of interest, and t is the time the money was accumulating interest. After cleaning up, you get in a situation due to you having e still lying around. Luckily, if you take the natural log of e, all you have left behind is the previous exponent. Thus, you can take the natural log of both sides, divide by 4, and then simplify to see that your final interest rate is ~6%
