The distance travelled by a particle starting from rest and moving with an acceleration `(4)/(3)ms^(-2)`, in the thrid-second is

A

`(10)/(3)m`

B

`(19)/(3)m`

C

6m

D

4m

Verified by Experts

The correct Answer is:

A

Distance covered in `n^(th)` second.
`S_(n)=u+(1)/(2)a(2n-1),`
`=0+(1)/(2)xx(4)/(3)(2xx3-1)`
`=(1)/(2)xx(4)/(3)xx5=(10)/(3)m`
