School project topic

[RanciD]

Hi, I need a topic to write a paper and do a presentation on for a trig class and I'm sure there's got to be some trigonometry involved in cars. What I need is a more specific topic that I can explain the use of trig for so anyone know something I can do? Suspension, engine, whatever, it doesn't matter.

Thanks :)

Prove that when a cop takes your speed by radar, you are actually going faster because they shoot the gun at an angle from the side of the road.

Not exactly a car, but the steering is similar.
