The oscillation of a body on a smooth ho...

The oscillation of a body on a smooth horizontal surface is represented by the equation,
`X = A cos (omega t)`
where, X = displacement at time t
`omega =` frequency of oscillation
Which one of the following graphs shows correctly the variation a with t?
Here, a = acceleration at time t
T = time period

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
A
Since, acceleration
`a=-omega^(2)x`
`=-omega^(2)A cos omegat`.
