A particle performs harmonic ascillations along a straight line with a period T and amplitude a The mean velocity of the particle averaged over the time interval during which it travels a distance `a/2` starting from the extreme position is:

A

`a/T`

B

`2a/T`

C

`3a/T`

D

`a/2T`

Text Solution

Verified by Experts

The correct Answer is:
C
`x=acos omegat`
`v=-aomega sinomegat`
`levge= (underset(0)overset(T//6) int ((-a omega sin omegat))) /underset(0) overset(T//6) (int dt) = (3a)/T`
