. What is the maximum constant speed with which a car can round a circular turn of radius 80.0 m ona flat road if the coefficient of static friction between tires and road isμs= 0.55

Maximum constant speed with which a car can round is 20.76 m/s.

Explanation:

We know, for car to be move on flat road without slipping its  centripetal force should not exceed static friction.

Therefore, maximum value of friction must be equal to centripetal force.

Therefore,

Now, putting all given values and .

We get ,

Hence, this is the required solution.

the arctic is a region of the planet, north of the arctic circle, and includes the arctic ocean, greenland, baffin island, other smaller northern islands, and the far northern parts of europe, russia (siberia), alaska and canada.
