.2*100*9.8=196.
Root applied by 196=14 so the answer is 14.

mv^2/r = u(friction)mg.
By using above formula "v" can be calculated.

Overturning is counterbalanced by lateral friction in order to prevent from skid.
Overturning (centrifugal force) = frictional force.
Mv^2/r = UN=Umg (m is cancelled out both side).
V^2/100 = .2*10,
V = √(2*100),
V = 14.142 m/s..
