If a body starts from rest and travels 120 cm in the 6 second then what is the acceleration

A

`0.20 ms^(-2)`

B

`0.027 ms^(-2)`

C

`0.218 ms^(-2)`

D

`0.03 ms^(-2)`

Text Solution

Verified by Experts

The correct Answer is:
C
`S_(n)=u+(a)/(2)(2n-1) rArr 1.2=0+(a)/(2)(2xx6-1)`
`rArr a=(1.2xx2)/(11)=0.218 ms^(-2)`
