Question

If this speed is based on what would be safe in wet weather, estimate the radius of curvature for a curve marked 50 km/h . The coefficient of static friction of rubber on wet concrete is μs=0.7, the coefficient of kinetic friction of rubber on wet concrete is μk=0.5.

    Answer:

    Explanation:

    v = 50 km / h

    = 13.89 m /s

    When a vehicle runs on a circular path , it is static friction which prevents it from getting overturned .

    static friction = μs mg

    centripetal force = m v² / R

    m v² / R = μs mg

    R = v² / μs x g

    = 13.89² / .7 x 9.8

    = 28.12 m .
