Which equation for impulse is correct, where F F\,F is force, t t\,t is time, m m\,m is mass, u u\,u is initial velocity, and v v\,v is final velocity?
impulse=m(v−u)\text{impulse} = m(v - u)impulse=m(v−u)
impulse=m(v−u)t\text{impulse} = m(v - u) timpulse=m(v−u)t
impulse=Ft\text{impulse} = \frac{F}{t}impulse=tF
impulse=m(v−u)t\text{impulse} = \frac{m(v - u)}{t}impulse=tm(v−u)
