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 = A_0 - A_1 t + A_2 t^2`. The initial velocity of the particle is.

A

`A_0`

B

`A_1`

C

`A_2`

D

`-A_1`

Text Solution

Verified by Experts

The correct Answer is:
D
The velocity of particle is `v = (dx)/(dt) = -A_1 - A_2 t`
At `t = 0, v = -A`
So, initial velocity is `-A_1`.
