A mass `m=100 ` gram is attached at the end of a light spring which oscillates on a frictionless horizontal table with an amplitude equalt to `0.16m` and time period equal to 2 second. Initially the mass is released from rest at `t=0` and displacement `x=-0.16` metre. The expression for the displacement of mass at any time `(t)` is

A

`x=0.16cos(pit)`

B

`x=-016cos(pit)`

C

`x=0.16sin(pit+pi)`

D

`x=-0.16sin(pit+pi)`

Text Solution

Verified by Experts

The correct Answer is:
B
At t=0 x=-A
`x=-0.16cos(pit)`
