7. [10 points] Captain Kirk and the spaceship USS Enterprise are resting from previous adventures at the point (1,2,0) in the xy-plane. At time t = 0, they resume their journey (with initial speed zero). Their acceleration is known to be described by a(t) = (V1,t,t-1). At what time and place (specify coordinates) will they return to the cy-plane?
