What is the ideal banking angle for a gentle turn of 1.20-km radius on a highway with a 105 km/h speed limit (about 65 mi/h), assuming everyone travels at the limit?

4.14°

Explanation:

given:

r = 1.2 km

v = 105 km/h

1) convert your given

a) r = 1.2 km to m = 1200m

b) v = 105 km/h  to m/s = 29.2 m/s

2) plug into your ideal banking angle equation

() = = 4.14°

b

explanation:

1= 26.17

2= 1.17

3=30.86

4=5.86
