For the vertical arc:weight of the car must be balanced by the centrefugal forcemg = mv2rwhere r is the radius of the arcr = v2g = 9
8×9 89 8 = 9
8diameter = 2r = 2×9 8 = 19
6 m

The speed limit of a car over a roadways bridge in the form of a vertical arc is 9.8 ms-1. Calculate the diameter of the arc.
