    Discern initial V w/o components?

    hi, thanks a bunch for your reply. Ok, so my V[SUB]i[SUB] in components is V[SUB]i[SUB][SUB]x[SUB]=V[SUB]i[SUB] cos(45) & V[SUB]i[SUB][SUB]y[SUB]=V[SUB]i[SUB]sin(45) ... Ok, and time can be written as: t =( V[SUB]f[SUB][SUB]x/y[SUB] / a) + V[SUB]i[SUB][SUB]x/y[SUB]...
