The motion of a particle is described by the equation at `u = at`.The distance travelled by the particle in the first 4 seconds

A

4a

B

12a

C

6a

D

8a

Text Solution

Verified by Experts

The correct Answer is:
D
`u = at rArr (dx)/(dt) = at rArr int dx = int_0^4 (at) dt`
`rArr x = [ (at^2)/(2) ]_0^4 = 8a`
