(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 =

that is 0 at

t = 0 and at t = 1/3

calculate x at t = 0 and at t = 1/3

then acceleration = 36 t - 6 = 6(6t-1)

calculate acceleration at whatever time
