Recall that the equation for projectile motion is given by

where , , and . Create a Geogebra applet to determine the suitable value of . Press ENTER after each input.
  1. v_0 = Slider(0, 20, 0.1)
  2. g = 9.81
  3. a = (2 * g) / (3 * (v_0)^2)
  4. b = 1 / sqrt(3)
  5. c = 20
  6. y = a*x^2 + b*x + c
