Question

A car is moving along a circular track with tangential acceleration of magnitude a₀. It just start to slip at speed v₀ then find radius of circle. (Coefficient of friction is µ)

G1 Physics · Accepted Answer

At impending slip, friction supplies both tangential and centripetal acceleration: (µg)²=a₀²+(v₀²/R)². Thus R=v₀²/√(µ²g²-a₀²). Hence B.
