Answer to Question #136286 in Physics for Jeremiah

Question

The motion of a car is described with t=Vf/a instead of t=Vf-Vi/a, what does the new equation tell me?

Answer 1

If we compare these equations, we will notice that if we substitute 0 for Vi into the second equation, it will become the first equation. Therefore, it means that the initial velocity in this case is 0.
