Thecoefficient of static friction for a car not to skid when traveling at
Answer to Problem 22P
Solution:
Explanation of Solution
Given:
Radius of curve
The curve is properly banked for a car traveling speed
Traveling speed of the car
Formula Used:
Static friction force
Centripetal acceleration
Where v : velocity of the body
R : radius of curvature
Banking angle can be obtained by:
Calculation:
Banking of road at
Conclusion:Hence, friction coefficient must be greater than or equal 0.32.
