I am completely stuck on this question and I have read through my text book and cannot find any relevant references to information I need, can anyone help?

A car is driving up a slope at angle 16 degrees to the horizontal, trying to accelerate as much as possible. The static and kinetic friction coefficients are 0.90 and 0.80 respectively.

Find the magnitude of the maximum possible acceleration (assuming a sufficiently powerful engine).

Sorry, i now realise that this belongs in the physics help forum.
