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
-
2 rad s-1
- 4 rad s-1
- 5 rad s-1
- 10 rad s-1
The correct answer is: A
Explanation
= \(\frac{v}{g} = \frac{0.2}{0.05}\)
where w = √ 4 → 2rad s-1
