Question

The pendulum of an antique clock has been damaged and needs to be
replaced. If the original pendulum completed one swing every 1.5 seconds,
how long should the new pendulum be? Use the formula:
T = 27.
1980
OA. 351 centimeters
B. 55.9 centimeters
OC. 234.8 centimeters
OD. 0.25 centimeters

Answer 1

The length of the giving swinging pendulum is; B: 55.9 centimeters

How to find the length of a swinging pendulum?

The formula to find the period of a swinging pendulum is;

T = 2π√(L/g)

where;

T is period

L is length

g is acceleration due to gravity = 980 cm/s²

We are given;

T = 1.5 s

Thus;

1.5 =  2π√(L/980)

(1.5/2π)² = L/980

L = 980 * (1.5/2π)²

L = 980 * 0.057

L = 55.9 Centimeters
