Answer:
The maximum speed is 21.39 m/s.
Explanation:
Given;
radius of the flat curve, r₁ = 150 m
maximum speed, = 32.5 m/s
The maximum acceleration on the unbanked curve is calculated as;
the radius of the second flat curve, r₂ = 65.0 m
the maximum speed this unbanked curve should be rated is calculated as;
Therefore, the maximum speed is 21.39 m/s.
