The displacement of an obuect attached to a spring and executing simple harmonic motion is given by `x=2xx100^(-2) cos pit` metre. The time at which the maximum speed first occurs is.

A

0.5 s

B

0.75 s

C

0.125 s

D

1.5 s

Text Solution

Verified by Experts

The correct Answer is:
A
Particle is initially at +ve extreme
Max speed at mean position `rArr t = (T)/(4)`
`T = (2pi)/(pi) = 2s rArr t = (2)/(4) = 0.5s`
