A 1199 kg mass car travels with a constant speed of v = 50 km/hour towards a hill that has a semicircular cross section of radius, R = 70 m in a region near the top of the hill as shown in the diagram below. The hill has a total height, 18 m. At the top of the hill, the force of friction the road exerts on on the tires is measured and found to be 107 N to the right. V. V In the box below, fill in the magnitude (in N) of the normal force acting on the car at the top of the hill? Please select units for your answer. In the work you submit for this question (but NOT in the box below), also show your work and determine the drag force (magnitude and direction) acting on the car from the friction with the air.
