## Homework Statement

cross-country skier is going up a slope at angle 5º to the horizontal. She is skating so only her skis provide the propulsion (i.e. she does not push with her ski poles). The static and kinetic friction coefficients for this situation are μs = 0.12, μk = 0.07 respectively.

what is the maximum accelleration she can obtain?

## Homework Equations

Fnet=ma

## The Attempt at a Solution

so far i have got to (0.17-0.02)*9.8 *cos85=a

which equates to 1.4m/s^2 is this correct?

I got it by dividing the 9.8*cos85 and the mass (which cancelled out).

Juswanted to know if its right as i dont have the answer and been working on it for a while.
