A constant velocity or acceleration just means either v(t)=k (m/s) or, separately, a(t)=k (m/s^2) where k is any real constant. This just means there is no rate of change, so the derivative of a constant velocity, which yields acceleration, is zero. That's why sometimes in a Newton's Laws problem they will say something travels with constant velocity, instead of saying there is no acceleration.
