A 600-kg car is going over a curve with a radius of 120 meters that is banked at an angle of 25 degrees with a speed of 30 meters per second. The coefficient of static friction between the car and the road is 0.3. What is the normal force exerted by the road on the car?

a) 7240 N
b) 1590 N
c) 5330 N
d) 3430 N
e) 3620 N

Note: The speed is not Vmax (roughly 32 m/s). I've been working under the assumption that mgcos(theta) will be increased by the frictional component acting downward. I simply can't seem to get the solution.

You can always use g = 10 or g = 9.8 m/s² and see which value is nearest among the answers.

So, the answer is above. In this question you have to find out the correct value for G. If not you won´t have the right answer.
