A particle moves along X-axis in such a ...

A particle moves along X-axis in such a way that its coordinate X varies with time t according to the equation `x = (2-5t +6t^(2))m`. The initial velocity of the particle is

A

`-5m//s`

B

`6m//s`

C

`-3m//s`

D

`3m//s`

Text Solution

Verified by Experts

The correct Answer is:
A
`x = 2 - 5t + 6t^2`
`v = (dx)/(dt) = -5 + 12t`
at t= 0, v =-5m/s
