Aparticle moves along the x axis. its position as function of time is given by x=6.8t+8.5t^2, where t is in seconds and x is in meters. what is the acceleration as a function of time?

As per the question the particle moves along X-axis.

The position of the particle is a function of time

As per the question the position

The velocity of the particle is given as

                                                                  v=6.8+17t

The acceleration of the particle is given as

                                               a=17

Here the acceleration is a constant quantity which is independent of time.

From the acceleration obtained here one can infer that particle is moving with uniform acceleration .
