Question

Disturbed by speeding cars outside his workplace, Nobel laureate Arthur Holy Compton designed a speed bump (called the Holly Humo) and had it installed. Suppose 1000-kg car passes over a hump In a roadway that follows the art of a circle of radius 18.4 m as in the figure below (a) of the car travels at 28.8 km/h what force does the road exert on the car as the carpasses the highest point of the hump? magnitude direction (b) What is the maximum speed the car can have without losing contact with the road as it passes this highest point? knih
