The position of a particle moving along an *x* axis is given by *x* = 13.0*t*2 - 5.00*t*3, where *x* is in meters and *t* is in seconds. Determine **(a)** the position, **(b)** the velocity, and **(c)** the acceleration of the particle at *t* = 6.00 s. **(d)** What is the maximum positive coordinate reached by the particle and **(e)** at what time is it reached? **(f)** What is the maximum positive velocity reached by the particle and **(g)** at what time is it reached? **(h)** What is the acceleration of the particle at the instant the particle is not moving (other than at *t* = 0)? **(i)** Determine the average velocity of the particle between *t* = 0 and *t* = 6.00 s.
