(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A firefighter whose weight is 812 N is sliding down a vertical pole, her speed increasing at the rate of 1.45 m/s2. Gravity and friction are the two significant forces acting on her. What is the magnitude of the frictional force?

2. Relevant equations

Fk = ukFn

uk = coefficient of kinetic friction

3. The attempt at a solution

I'm not sure what the coefficient of KF should be so I just tried ..

812*1.45 = 1177.4

I'm not sure how to incorporate the gravity and friction into the equation.
