# Homework Help: Velocity question

1. The problem statement, all variables and given/known data
I have been given the force, mass and the time, and I need to find the velocity, and I only have the formula $v=at$

2. Relevant equations
$v=at$

3. The attempt at a solution
From the Newton's second law we know that $a=\frac{F}{m}$,
So Can I just do $v=\frac{F}{m}t$, or do I need to find acceleration $a$, then just go with the formula $v=at$?

They amount to the same thing.

I don't think they amount the same on this task because i only been given the formula $v=at$ so we would define that formula as $v=\frac{Ft}{m}$.

Which, again, is the same thing algebraically.

Maybe so, but how the task needs it to be, I think it's different

I'm not sure what the distinction you're trying to make is.
