Question
A roadway is designed for traffic moving at a speed of 94 m/s. A curved section of the roadway is a circular arc of 740 m radius. The curved section is temporarily replaced with an unbanked roadway of the same radius. The coefficient of friction of this roadway is 0.40. The maximum safe driving speed for this unbanked, curved section is closest to: Select one: a. 52 m/s b. 54 m/s c. 50 m/s d. 46 m/s e. 48 m/sPlease explain the answer so i can understand how you got it :) A roadway is designed for traffic moving at a speed of 94 m/s.

Explanation / Answer
A = inverse tangent(v^2/rg)
A = tan-1 (94(94)/740(9.8)) = 50m/s
which is option c
