# Inclined plane and banked Curve HSC Questions

Banked Curve HSC Questions often require students to approach the problem from a mathematical perspective. The good news is this can be learnt using a method which repeatable and can be systematised. This way you get the right answer every time.

An inclined plane and banked curve problem can be approached in the following way:

The formula to remember, which is not included on the HSC formula sheet is the following:

Most questions encountered can be solved with this formula. Notice the masses will cancel out, so the maximum safe velocity is determined by the radius of the turn, the angle of the incline and the gravitational acceleration.
