A loaded spring performs simple harmonic motion with an amplitude of 5cm. If the maximum acceleration of the load is 20cm s-1, calculate the angular frequency of the motion
A
2 rad s-1
B
4 rad s-1
C
5 rad s-1
D
10 rad s-1
Verified Correct Answer: A.
Physical Principles & Numerical Solution
= \(\frac{v}{g} = \frac{0.2}{0.05}\)
where w = \sqrt 4 → 2rad s-1
