Homework Statement



A person is running down a hill which is a 30° downward slope. If the coefficient of kinetic friction is 0.10, what is acceleration of the runner.

Homework Equations



Fnet=F┴-Ff


The Attempt at a Solution



Since we are only given 2 known things, the θ is 30° and the kinetic friction is 0.10. I am wondering if I am using the correct formula and need to be pointed in direction of what else to find to actually find the acceleration. I know we need Fnet but that is not all.

Ok I have found out the answer one way by just doing a = 9.81 x (0.5-0.10(0.866)) but is there a different way to find the answer or is this the only one? I mean by finding Fnet and somehow answering it a different way?
