Oscillations

A simple harmonic oscillator has an amplitude A and time period 6 second. Assuming the oscillation starts from its mean position, the time required by it to travel from x=A to x= 32 A will be x s, where x= .

Answer

2

Solution

[figure]

Measuring time from the extreme P: x=A t

= 2 T= 2 6 = 13 rad s-1

32A=A t t= 6

t= /61/3= 2 s

x=2
