Question

suppose a cyclist is negotiating a curve of radius r with speed v .write the condition under which skidding will occur

Answer 1

The maximum velocity with which a vehicle can go around a curve of radius 'r' without skidding is
$\sqrt{urg}$
where u is coefficient of static friction between road and vehicle.
r is radius of curvature of that path.


Steps:
1) Radial force <= friction force (max)
