A huge SUV of mass 2300 kg can accelerate from 0 to 60 mi/h in 9.0 s. What force does the road exert on the SUV?

V_{0}= 0

V= 60mph or 26.8224m/s

M= 2300kg

t=9s

2. Relevant equations

F=ma

3. The attempt at a solution

a= (26.8224) / 9 = 2.98

F_{x}= ma = 2.98*2300 = 6854.61 N

F_{y}= m*g = 2300*9.8 = 22540 N

So those are the two forces that I was able to calculate but I am not sure how I find the force exerted by the road on the car. Any help would be greatly appreciated! Thanks!

other info: I read somewhere that the force would be sqrt (Fx^{2}+ Fy^{2}) but that didn't give me the right answer if my above work is correct.
