1.6 Hz
Explanation:
In simple harmonic motion, acceleration is given by the formula;
a = Aω²
Where;
A is amplitude
ω is angular velocity.
We are given A = 9.7 cm = 0.097 m
We know that acceleration due to gravity is 9.8 m/s².
Thus;
9.8 = 0.097ω²
ω² = 9.8/0.097
ω = √101.031
ω = 10.05 rad/s
Formula for frequency is;
f = ω/2π
Thus;
f = 10.05/2π
f = 1.6 Hz
