Question

Two cars, one with and one without ABS, are stopping from the speed v0 = 100 km/h by full breaking. The first without ABS by blocking the wheels, i.e. sliding (’kinetic friction’), the second with ABS with still rolling wheels (ideal ’limiting static friction’ assumed). Determine for both cars the time tB and the distance sB for stopping if the coefficients of static and kinetic friction between pavement and tire are μ0 = 0.7 and μ = 0.45, respectively.
