Homework Statement
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?
Homework Equations
Normal Force - Weight = [mass(velocity^2)]/radius
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?
