### STEP Mechanics - What Do You Need to Know?

##### Stage: 5 Challenge Level:

What do you need to know to be able to tackle Mechanics STEP questions?

### Modelling Assumptions in Mechanics

##### Stage: 5

An article demonstrating mathematically how various physical modelling assumptions affect the solution to the seemingly simple problem of the projectile.

### Model Solutions

##### Stage: 5 Challenge Level:

How do these modelling assumption affect the solutions?

### Whoosh

##### Stage: 5 Challenge Level:

A ball whooshes down a slide and hits another ball which flies off the slide horizontally as a projectile. How far does it go?

### Out in Space

##### Stage: 5 Challenge Level:

A space craft is ten thousand kilometres from the centre of the Earth moving away at 10 km per second. At what distance will it have half that speed?

### Wobbler

##### Stage: 5 Challenge Level:

A cone is glued to a hemisphere. When you place it on a table in what position does it come to rest?
