    Projectile Motion: Finding Height & Time for Archer's Target Shot

    this is what I did. Solve for T Change of X = V initial (x component) * t 125 = (cos15)(50)t t = 2.6s That is the first part and answer for (B), then I tried to solve for A through through the following steps: Change of Y = V initial (Y component) t + 1/2 a(component y) * t^2 Y -...
