If a body moving with an initial velocity of 3 m/s and an acceleration of `2 m//s^2`. Then what will be the distance travelled by the body in 4th second.

A

6 m

B

7 m

C

10 m

D

28 m

Text Solution

Verified by Experts

The correct Answer is:
C
`s = u + a/2 (2n - 1)`
`implies s = 3 + 2/2 xx (2 xx 4 xx (-1)) = 3 + 7 = 10 m`
