What is the maximum speed with which a 1070 kg car can round a turn of radius 80 m on a flat road if the coefficient of static friction between tires and road is 0.80?

  • Physics - ,

    Matching the centrifugal force with the frictional resistance,
    μmg = mv²/r
    solving for v,
    v=√(μgr)
    =25 m/s
    This is assuming that there is no superelevation built into the bend.
