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?

Answer 1

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.
