if a ball, fired as a projectile, travels 30 meters when it leaves the the ground at 20% angel, it will travel the same distance when fired at an angle of what degrees

  • physics -

    Is "20% angel" supposed to be "20 degree angle"? Or is the ball still earning its wings?

    I will assume you mean 20 degree angle.

    Range = (V^2/g)*sin(2A)
    (Try to derive that yourself)

    For A = 20 degrees, 2A = 40.
    You get the same value for the sine, and the range, when 2X = 140. That means A = 70 degrees.
