A body moves on a horizontal circular road of radius of r, with a tangential acceleration a_(T) . Coefficient of friction between the body and road surface is mu . It begin to slip when it's speed is v , then :

A 60kg man is running on horizontal road with acceleration 2ms^(-1) friction coefficient between foot of the man and the ground is mu=0.4 then
