No force causes the car to do this because the car is traveling at constant speed and therefore has no acceleration. |
The normal force from the road because if the car is on a banked turn, the normal force (which is always perpendicular to the road's surface) is no longer vertical. The normal force now has a horizontal component, and this component can act as the centripetal force on the car. Given just the right speed, a car could safely negotiate a banked curve even if the road is covered with perfectly smooth ice!

A car goes around a curve on a road that is banked at an angle of 33.5 degree. Even though the road is slick, the car will stay on the road without any friction between its tires and the road when its speed is 23.0 m/s. Part A What is the radius of the curve?
Help please I don't no how to do these The curved section of a horizontal highway is a circular unbanked areof radius 760 m. If the coefficient of statiefriction between this roadway and typical tires is 0.40m, what would be the maximum safe driving speed for this horizontal curved section of highway? When a car goes around a banked circular curve at the proper speed for the banking angle, what force cause it to follow the circular path? gravity the...
Two cars are driving around a banked curve at a speed that is not too fast. One car has really good tires (has lots of traction) and the other car has bad tires (bald with little traction). Which of these cars is more likely to slide on the pavement as it goes around the curve? Two cars are driving around a banked curve at a speed that is not too fast. One car has really good tires (has lots of traction)...
X Incorrect. Engineering a highway curve. If a car goes through a curve too fast, the car tends to slide out of the curve. For a banked curve with friction, a frictional force acts on a fast car to oppose the tendency to slide out of the curve; the force is directed down the bank (in the direction water would drain). Consider a circular curve of radius R and bank angle, where the coeffcient of static friction between tires and...
5. (10 pts): A car of mass M goes around an icy banked turn of radius t at a speed v. If there is no frictional force and the car takes the turn without skidding, at what angle 0 is the turn banked?
Banked Frictionless Curve, and Flat Curve with Friction Reviev A car of mass M - 1300 kg traveling at 60.0 km/hour enfers a banked turn covered with ice.

A toy car of mass 0.35 kg travels along a circular banked road, with banking angle 30°. The circle has radius 0.80 m. Sarah wants to make the car move as fast as possible, but if it goes too fast, it slips off the road. Therefore, Sarah cuts a 0.80- meter piece of string, attaches one end to the car, and attaches the other end to a nail stuck in the center of the circle. Unfortunately, the string is thin...
a. Calculate the maximum safe speed for a 2 ton car traveling around a curve with a radius of 150 yards given a force of friction of 650 N. Provide your answer in m/s and mph. At the maximum safe speed, what is the centripetal acceleration of the car? Given that the force of friction remains 650N, if the car is traveling at twice the maximum safe speed around a curve with a radius that is twice as large, will...
