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

What power is needed to drive a car at 60 km/h up a 10% grade.

mass=1800kg

v=60km/h

theta=5.7106

g= 9.81 m/s^2

2. Relevant equations

P = Fv

P_ave= W/T

w=mg

F=ma

3. The attempt at a solution

I drew my diagram and FBD.

Since Fy=mAy=0..

0=N-sin(5.7106)

N=1755.2477

I know that Ax will be 0 since the velocity is constant, and I need to find the frictional constant:

mAx=0=F-uk-mgcos(5.7106)

But I don't have F, since it's what I'm trying to find..and this is where I've been stuck.
