    Projectile motion of half a parabola

    Vi for Y is 0, so I would need to use the formula to find the time, which is .77 seconds, so with this I can find Dx right?

    Projectile motion of half a parabola

    I don't think I can use it because all I really know in that formula is Vi and Acceleration
