    A projectile of mass 0.552 kg is shot from a
    cannon, at height 7 m,
    with an initial velocity vi having a horizontal
    component of 5 ms.
    The projectile rises to a maximum height of
    Y above the end of the cannon's barrel and
    strikes the ground a horizontal distance X
    past the end of the cannon's barrel.
    The acceleration of gravity is 9.8 ms^2 :

    Determine the vertical component of the
    initial velocity at the end of the cannon's bar-
    rel, where the projectile begins its trajectory.
    Answer in units of ms.

    Determine the maximum height Y the pro-
    jectile achieves after leaving the end of the
    cannon's barrel. Answer in units of m.

    Find the magnitude of the velocity vector
    when the projectile hits the ground. Answer
    in units of ms.

    Find the magnitude of the angle (with repect
    to horizontal) the projectile makes when im-
    pacting the ground. Answer in units of degree.

    Find the range"x" of the projectile. Answer
    in units of m.
