"Calculate the height reached by a water powered rocket using right-angled trigonometry in this practical activity." These impressive little water powered rockets go high, really high! But what kind of height will yours reach? 20m, 30m, 50m, ... (the world record is over 300m!) There is really only one way to find out, and that is to use right-angled triangle trigonometry. In this practical activity you will be working...
