1. The problem statement, all variables and given/known data Disturbed by speeding cars outside his workplace, Nobel laureate Arthur Holly Compton designed a speed bump (called the "Holly hump") and had it installed. Suppose a 1 800-kg car passes over a hump in a roadway that follows the arc of a circle of radius 21.4 m as in the figure below. (a) If the car travels at 28.5 km/h what force does the road exert on the car as the car passes the highest point of the hump? 2. Relevant equations Normal Force - Weight = [mass(velocity^2)]/radius 3. The attempt at a solution I used the equation above and converted the velocity to m/s which i got 7.9166 Then basically plug n chug. My final answer was 22911.6 (sig figs doesn't matter here) But when I submitted my answer it says my answer is off more than %10 of the actual answer. Any suggestions?
