force ,mass,and initial velocity?

i know abought F=MA,but is ther a way to find initial velocity useing F and M[like if i apply a force of X to a mass of Y,its initial velocity will be great enough to propel it 50 meters upwards]

    Accelerattion A = F/M = X/ M, since F = X.

    Accelerattion A is {cahnge in velocity / Time} = V- U / T

    V = 50m/s. U = ?

    X/ M = 50 - U / T.

    There are four quantities involved in this equation. X, M, U and T.

    If any of the three quantities is known then the other can be found.

    thats e=mc2 mc is accelaration x mass = force or power equals how quick you can move something. initial velocity is the speed. that has no relevence in space as there is no gravity. e=mc2 no hard to unders stand universe is = mass times acceletration. universe means e in that equation lol.

    you would need one of the kinematic equasions to do that. mainly

    (final velocity)^2 = (initial velocity) + 2(acceleration)(distance)

    If acceleration is constant

    F = ma

    x(t) = 0.5 a t^2 + v0 t + x0

    =====================

    So if a = g (note g is a negative number)

    dx/dt = a t + v0 = 0

    t = -v0/a

    plug that back in to get max height.

    x(max) = 0.5 v0^2/a - v0^2/a + x0 = x0 - 0.5 v0^2/a

    You can flip the equation around, therby enabling f/m=a or f/a=m.
