There is a multitude of acceleration velocity formulas in the study of physics. One of the many acceleration velocity forumlas is the fourth kinetics equation. This equation is as follows: vf^2 - vi^2 = 2a(xf-xi). It can be re arranged as such to properly make this equation accurate: vf^2 = vi^2 + 2ad where d is the distance travelled under accel. Use this equation to solve most problems where
. time is not given. Another acceleration velocity formula is the 3rd Kinematics equation. Physicists typically use it to solve problems where vf is not given.
