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.
