A particle performs simple harmonic motion with amplitude A. Its speed is trebled at the instant that it is at a distanc
from equilibrium position. The new amplitude of the motion is :
As we learnt in
Relation of velocity and displacement -
- wherein
x is displacement from mean position
A is Amplitude.
We know that
,
Initially -
Finally - Final amplitude
Now dividing we get
After calculate we get
