Torpedo Challenge
You are positioned at (3, 0) and can fire torpedoes to stop the submarine. It takes 1 second to calculate and enter the direction of your torpedo shot. What direction should you fire your torpedo?
•	Use the Geogebra applet and sink the submarine. 
•	Press play to see what happens.
•	Change the direction of the torpedo by entering different numbers in red.
•	You can recreate a different situation if you ‘change the submarine’.
