You are concerned about the moon roof on your new sports car. it seems to flex when you drive at high speeds. calculate how much net fore the moon roof must withstand and in what direction. assume the moon roof is flat with an area of 0.5m2, and the pressure and velocity over the moon roof are constant. your driving speed is 20 m/s and the velocity over the moon rood is 30m/s. the pressure inside the car is 90,500 n/m2, and the freestream pressure and density in front of the car are 90,000 n/m2 and 1.1 kg/m3. (hint: draw a sketch)

alright, so i know from the solutions in th back of the book that the answer is f=387.5 n (outward), but i can't get there. i think i need to use bernouli's equation but i'm not really sure about that either.
