The position of a particle is given by the function x = ( 6 t^3 - 3 t^2 + 2) m, where t is in s.

(a) At what time or times is vx = 0 m/s? (Enter NONE for t2 if there is only one time.)

Smaller time, t1 =

Larger time, t2 =

(b) What are the particle's position and its acceleration at this time(s)? position at time t1 =

acceleration at time t1 =

position at time t2 =

acceleration at time t2 =
