Calculate the velocity from acceleration

Hi,

I want to calculate the velocity for year 2013,2014,2015 and 2016 from the rate given for 2013-2016 m/year.

%acceleration is scalar 57013*1 %time is 4*1 (for 2013-2016)

Can anyone point me in the right direction?

Thanks

Is velocity rate a weird term for acceleration?

If you only have acceleration without an initial velocity then it is not possible to calculate the velocity.

velocity = acceleration * time + initial_velocity
