Quadratic Applications

• An archer shoots an arrow into the air. The
  height of the arrow in terms of its distance from
  the archer is given by the equation
• Where h is the height and s is the horizontal
  displacement Assuming 0 is the position from
  which the arrow is shot, and that it was shot
  over level ground find
• A) The how far above the ground the arrow is when
  it has travelled 20m from the archer.
• B) How far above the ground the arrow is 70m
  above the archer.
• B) The height that it was shot from (that is how
  high above the ground the archers arm was).
• C) How far the arrow travels before it hits the
  ground.
