The trick to this unit is simply to do lots of calculations over and over again. Test out what you think, try out the animations and you will be able to do the exam questions. The nuts and bolts are important for every calculation. Try to set up each problem with a diagram and then apply one of the UAM equations. If the problem is setup correctly you cannot go wrong. Don’t try and wing it!

I have now worked out every problem in the test book for this unit and answers are shown below so if you need help then here is a place to start.

How to do calculations involving horizontal projectiles.
