Enter parameters for the red ball so that it follows the blue path, then click 'GO':

x(t) =       y(t) =
STONE

Click (re)start. The applet simulates a stone thrown upwards at an angle from a high cliff, and then it falls to below.

Use the information in the animation to find:
  1. The horisontal and vertical component formulas of the position of the stone in terms of the time t.
  2. How high does the stone rise?
  3. The position (i.e. x-y co-ordinates) of the stone after 8 seconds.

Now check your formulas in the applet.
