Vo = 6m/s
a = 1.8 m/s2
D = 1500m
And we also know that:
 Replacing the known values:
   Replacing the known values:
 Solving for t we get 2 possible answers:
    Solving for t we get 2 possible answers:
t1 = -44.3s   and t2 = 67.7s    Since negative time represents an instant before the beginning of the movement, t1 is discarded. So, the final answer is:
t = 67.7s
