Parabolic Motion, equation for t

  1. Oct 18, 2012 #1
    I'd like to know why

    t= v - u/a

    will not get me a correct value for t when v= final velocity, u= initial velocity and a=acceleration, when the final velocity of the projectile along the y axis=0.

    I hope you mean t= (v - u)/a.
    Please show your working so that we can see where you go wrong. Are you perhaps forgetting to make a negative?

    What do you mean with "parabolic motion"?
    Maybe the acceleration is not constant?
