Question

A flat curve on highway has a radius of curvature 400m a car roundsthe curve at a speed of 32m/s what is the minimum value of coefficient of friction

Answer 1

Answer:

Coefficient of friction, μ = 0.256

Explanation:

We know that v²=μrg

32 × 32 = μ × 400 × 10

μ = 32 × 32 / 4000

μ = 0.256
