Another (equivalent) way is to use the "impulse-momentum" theorem: [itex]F \Delta t = m \Delta v[/itex].

i'm terrible at math, can you isolate time on one side of the equation?

[tex]t = \frac{v_f - v_i}{a}[/tex]Serj said:Vf=Vi + at

Make note of what ZapperZ said, though.

cscott has done this for you, but you won't get very far with physics if you don't first brush up on elementary algebra. I strongly recommend you learn the math first.Serj said:i'm terrible at math, can you isolate time on one side of the equation?
