Homework Help: Projectile motion

  1. May 7, 2012 #1
    how to get to Vo = the square root of ((xa)/(sin2theta))
    from the kinematic equations or form SinTheta =Voy/Vo CosTheta =Vox/Vo

    just really confused. im writing a formal lab for my final and what im asking is find the initial velocity it would take for the object to hit the target as a given angel

    i have tried to derive the kinematics formulas as well as the sectors for the initial velocity
