Answer:

f = 0.365 Hz

Step-by-step explanation:

The angular velocity of a simple pendulum is

w =
√(g/L)

angular velocity and frequency are related

w = 2π f

we substitute

2π f =
√(g/L)

Let's find the initial length of the pendulum

L =
(g)/(4\pi^2 ) \ f_o

L₀ =
(9.8)/(4 \pi ^2) \ 0.4

L₀ = 0.6206 m

Indicates that the length of the chord triples

L = 3 L₀

L = 3 0.6206

L = 1.8618 m

let's find the frequency

f =
(1)/(2\pi ) \ \sqrt{(9.8)/(1.8618) }

f = 0.365 Hz
