The relationship between velocity, distance, and acceleration can be given as

v^2 = 2*a*d

when the starting or ending velocity is zero. You have

v^2 = 2*(.4 m/s^2)*(10 m) = 8 m^2/s^2

v = √8 m/s =

It will take a little over 7 seconds to reach that velocity.

**2√2 m/s**≈**2.83 m/s**_____It will take a little over 7 seconds to reach that velocity.
