Answer:
If the frequency of the motion of a simple harmonic oscillator is doubled , then maximum speed of the oscillator changes by the factor 2
Explanation:
We know that in a simple harmonic oscillator the maximum speed is given by
=
Here A is amplitude which is constant , so from above equation we see that maximum speed is directly proportional to of the oscillation .
Since
= 2
Where is the maximum speed when frequency is doubled .
