Suppose that the equation of motion for a particle (where s is in meters and t in seconds) is
s = t^4 - 2 t^3 + 6 .

(a) Find the time (other than att=0 when the acceleration is 0.

(a) Find the time (other than at

Acceleration is 0 at time

(b) Find the position and velocity at this time.

Position =

Velocity =
