The coefficient of kinetic friction for a 26-kg bobsled on a track is 0.13. What force is required to push it down a 4.1° incline

and achieve a speed of 7.0E1.0 km/h at the end of 73 m?

2. Relevant equations

Force friction=F*k

v_f=v_0+a*t

x_f=x_0+v_0*t+0.5a*t^2

v_f^2=v_0^2+2*a(x_f-x_0)

x-x_0=[(v_0-v+v_f)/2]*2

And just sum of forces=0

F=ma

3. The attempt at a solution

I'm lost...
