1. For constant acceleration, velocity is given by . Since presumably the dart's initial velocity was 0, we can say that meters per second.

2. For constant acceleration, displacement is given by . Initial displacement 0 and initial velocity 0 means that meters.

Substituting from 1:



You can finish the rest. Time is in seconds.
