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

A skier of mass 57 kg skis down a 10° slope @ constant velocity.

The force of air resist. has a magnitude of 74 N. Find the frictional force on the skis.

2. Relevant equations

F=ma

F(fr) = (mu)(Fn)

3. The attempt at a solution

I found Fn= ma

where is 558N

so far i tried, 74sin10- 558

and i tried drawing a body diagram, where 558 is directly upwards, 9.8 down for gravity, the downward slope of 74 N at 10 deg
