    How to find initial velocity from range and angle.

    Vf=Vi+-9.8x(25/Vi.cos30) 0=v-9.8x(25/v.cos30) v=9.8x(25/v.cos30) u∧2cos30=9.8x25 u∧2=(9.8x25)/cos30 u= square root((9.8x25)/cos30) u=16.8196799??

    How to find initial velocity from range and angle.

    Ah.. what do I use the vertical height for? 25tan30= 14.43375673 so then, Uv=0 Height?=14.43375673

    How to find initial velocity from range and angle.

    if s=0 it's simplified to u= (square root of 9.8x50)/cos30 and the answer is 23.78661943 but if s=50 the answer is 27.80110847 What is correct? and why? Please help

    How to find initial velocity from range and angle.

    I tried working it out... Uv= usin30 Uh= ucos30 t= d/Uh, t= 50/ucos30 s=Uv.t+(1/2).-9.8∧2 and does s=0? I can't remember why. 0=usin30.(50/ucos30)+(1/2).-9.8.(50/ucos30)∧2 0=? how do i simplify this?

    How to find initial velocity from range and angle.

    t= d/u, so t=d/ucos30. Do I leave it as that or.. t= 50/ucos30?

    How to find initial velocity from range and angle.

    Could you give some advice in how I would do that? Like which formula to use? Can it be figured out using these formulas?
