The distance s travelled by a particle m...

The distance `s` travelled by a particle moving on a straight line in time `t` sec is given by `s=2t^(3)-9t^(2)+12t+6` then the initial velocity of the particle is

A

6

B

`-9`

C

12

D

11

Text Solution

Verified by Experts

The correct Answer is:
C
`s=2t^(3)-9t^(2)+12t+6`
`v=(ds)/(dt)=6t^(2)-18t+12`
At `t=0, v=6(0)-18(0)+12=12`.
