  1. Ignoring the target position, shoot the bullet now.
  2. Pause the motion when the bullet strikes the ground. Use the step frame buttons (>> or <<) as needed to position the ball precisely at ground level.
  3. Note the x-coordinate of the bullet and enter this as the Target Position.
  4. Shoot the bullet to verify that you hit the target this time.
  5. Determine a second angle for which the bullet hits the target in the same position.
  6. Change the angle to 25° and repeat steps 1-5.
  7. Now select 15° and repeat steps 1-5 again. Do you see a pattern emerging? What is it?
