The position of a body moving along the [math]-axis is given by [math], with [math] in meters and [math] in seconds.

(a) Find the body's acceleration each time the velocity is zero. If there is more than one answer, enter a comma separated list. If there are no answers, enter NONE.
Acceleration = [math]

(b) Find the body's velocity each time the acceleration is zero. If there is more than one answer, enter a comma separated list. If there are no answers, enter NONE.
Velocity = [math]

(c) Find the total distance traveled by the body from [math] to [math].
Total distance = [math]
