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
Correct Answer: Option B
Explanation
w = (frac{v}{g} = frac{0.2}{0.05})
= 4 rad s-1
