5. The department of transportation decides to make a very large speed bump in the shape of part of a circle with radius (to the center of mass of the car) of 12.3 m. A car of mass 1920 kg drives over the speed bump (hence undergoes circular motion) and has a speed of 6.9 m/s at the top. At this point, what is the magnitude of the normal force from the speed bump on the car? A. 11.40 kN В. 7.43 kN С. 18.8 kN D. 26.27 kN E. 9.42 kN
