Find the angle of banking for a highway curve of 90 meters radius designed to accommodate cars traveling at 160 kph, if the coefficient of friction between the tires and the road is 0.60. What is the rated speed of the curve?

A flat (unbanked) curve on a highway has a radius of 220.0 m. A car rounds the curve at a speed of 25.0 m/s. (a) What is the minimum coefficient of friction that will prevent sliding? (b) Suppose the highway is icy and the coefficient of friction between the tires and pavement is only one-third what you found in part (a). What should be the maximum speed of the car so it can round the curve safely?

A car has to move on a level turn of radius 45 m. If the coefficient of static friction between the tyre and the road is µ, = 2.0, find the maximum speed the car can take without skidding.

A 10.1 kg box is released on a 49.9° incline and accelerates down the incline at 0.07 m/s². What is the coefficient of kinetic friction between the two surfaces?

An engineer wants to design an oval racetrack such that 3.20 × 10³ lb racecars can round the exactly 1000 ft radius turns at 1.00 x 102 mi/h without the aid of friction. She estimates that the cars will round the turns at a maximum of 175 mi/h. Find the banking angle necessary for the race cars to navigate the turns at 1.00 × 10² mi/h without the aid of friction. 0 = What additional radial force F, is necessary to prevent a race car from drifting on the curve at 175 mi/h? This banking and radius are very close to the actual turn data at Daytona International Speedway, where 3.20 × 10³ lb stock cars travel around the turns at about 175 mi/h. 0 Fr= N

a person on a bicycle is traveling on a curve of radius 48.0 m. if the rider is moving at 10.2 m/s, what is the minimum coefficient of kinetic friction necesarry to keep the biker on the road?

A car of mass 622 kg is driving around a curve with a circular arc of radius 20 m. If the car drives at a speed of 12 m/s, what is the minimum value of the coefficient of friction between the car's tires and the road that will keep the car on the road?
