We are building a road, and at one place we need to make a turn with a radius of 30m. The coefficient of static friction between rubber and the material we are using is 0.6. Assuming that the road is flat through the turn, what is the maximum speed a car could have and safely navigate the turn without sliding off the road? Instead of keeping the road flat, let's bank the turn a little bit, giving the road an angle of 20∘ above the horizontal. With the banked turn, what is the maximum speed a car could have and still make it around the turn without sliding?

Consider again the problem of a car traveling along a banked turn. Sometimes roads have a "reversed" banking angle. That is, the road is tilted "away" from the center of curvature of the road. If the coefficient of static friction between the tires and the road is μs = 0.4, the radius of curvature is 25 m, and the banking angle is 14°, what is the maximum speed at which a car can safely navigate such a turn?

Spy Agent 001 is chasing the bad guys. Suddenly, 001 needs to turn his car (m = 1000 kg) around, and completes a turn in the shape of a semi-circle (radius = 60 m) travelling at a constant speed of 27 m/s. a) If the static coefficient of friction between the tires and the pavement is 0.55, find the maximum force of friction before slipping occurs. b) Will the car be able to complete the turn without sliding? c) To...

The radius of curvature of a highway exit is r = 95.5 m. The
surface of the exit road is horizontal, not banked. (See
figure.)
If the static friction between the tires and the surface of the
road is ?s = 0.408, then what is the maximum speed at
which the car can exit the highway safely without sliding?

Two curves on a highway have the same radii. However, one is
unbanked and the other is banked at an angle of degrees. A car can safely travel along the
unbanked curve at a maximum speed under conditions when the coefficient of
static friction between the tures and the road is . The banked curve is frictionless, and the
car can negotiate it at the same maximum speed . Find the coefficient of static friction
between the tires and the...
