A particle moves along the x axis as
x=(t -2) + a(t -2)^2, where u ,a are constants and time t is in seconds.
it's really very tough plz help me!!!!!
ARMY PLEASE HELP!!

Relation given.
Taking symbol as normal meanings.
a = constant.
X = distance.
A = acceleration.
- Case-1
Differentiating w.r.t time.
will give velocity.
Using Product rule of Calculus.
Again differentiating w.r.t time
will give acceleration.
Acceleration of the particle is 2a m/s².
- Case-2
Taking times t = 2 seconds in the distance formula.
which will give.
so, the particle will be at origin at t = 2 seconds.

From the Question,
"x" is defined by the relation:
Differentiating x w.r.t to t,we get velocity of the particle:
Using Product Rule,
Differentiating a w.r.t to t,we get acceleration of the particle:
- Acceleration of the particle is 2a m/s²
Putting t = 2 in the distance function,we get:
As x = 0m,the particle is at origin
