What is the maximum speed with which a 1200- kg car can round a turn of radius 90.0 m on a flat road if the coefficient of static friction between tires and road is 0.55?

The maximum speed with which a 1200- kg car can make a turn is 22.02 m/s.

Maximum speed of the car

v(max) = √μrg

where;

  • μ is coefficient of friction
  • r is radius of the curved road
  • g is acceleration due to gravity

v(max) = √(0.55 x 90 x 9.8)

v(max) = 22.02 m/s

Thus, the maximum speed with which a 1200- kg car can make a turn is 22.02 m/s.
