Centrifugal force = Friction force,

mv^2/r = friction * mg.

Can a car move without friction?

Sai manoj said:   8 years ago
It's very simple sum because
Velocity(V) = ?.
Radius(R) = 100m,
Co-efficient of friction(f) = 0.2,
Gravitational force(g) = 9.8.

V=F * V * G.
V^2=0.2 * 100 * 9.8 = 196underroot,
v = root 196,
V = 14m/s.
