## Homework Statement

Hey there :), I am in year 11 and my teacher has assigned me with this "challenging question".

12. A motorcyclist leans his machine over so that it makes an angle of 55 degrees with the surface of the track as he negotiates a corner.

a.) If (due to the treat on his tyres and track conditions) he is able to safely do this up to a maximum speed of 100 km h^-1, what is the smallest radius of curvature that the corner can have?

## Homework Equations

Centripetal Force and acceleration

## The Attempt at a Solution

I rearranged tan(theta)= v^2/gr

to make r the subject.

But the answer is completely different to what the textbook says is the answer.

Answer: 112m

Any help would be greatly appreciated, I really want to do well in physics this term!
