Reason out the quantities v0, vf, Dv, vAve, a, Ds and Dt: If an object’s initial velocity is 9 cm/s, and it accelerates uniformly through 126 cm in 12 seconds, then what is its final velocity?

Using the equations which govern uniformly accelerated motion determine vf, v0, a, Ds and Dt for an object which accelerates through a distance of 126 cm, ending with velocity 9 cm/s and accelerating at .25 cm/s/s.
