A car encounters an inclined plane

Given- Weight of car in N (6500), velocity on the flat surface (22.5 m/s), power of the engine (78000), incline of the hill (8.1 degrees)

Want to find- velocity on the hill (power and restistive forces remain constant)

2. Relevant equations

P = Fvcos(theta)

3. The attempt at a solution

I found F by plugging in the power and velocity. I then subtracted the gravitational force due to the hill from this number to get the resultant force. plugged this in to P = Fvcos(theta) and got a number bigger than the original...

urgent help would be greatly appreciated since HW is due in 8 minutes, but i'm more worried about the concept for the test tomorrow. thanks.
