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

Options

A. `0.20 m//s^2 `
B. `0.027 m//s^2`
C. `0.218 m//s^2`
D. `0.03 m//s^2`

Answer

C

Explanation

`S_n = u + a/2 (2n-1)`
`rArr 1.20 = a/2 (6 xx2 - 1)`
`rArr a = (2 xx 1.2)/(11) = (2.4)/(11) = 0.218 m//s^2`
