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?

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!
