- Problem 9: Circular turns of radius r in a race track are often banked at an angle 0 to allow the cars to achieve higher speeds around the turns. Assume friction is not present, and use the coordinate system specified. F,Circular turns of radius r in a race track are often banked at an angle 0 to allow the cars to achieve higher speeds around the turns. Assume friction is not present, and use the coordinate system specified. Assume that the car is moving at 21 m/s and the radius of the track is 420m. What is the angle 0 in degrees?A car enters a level, unbanked semi-circular hairpin turn of 300 m radius at a speed of 40 m/s. The coefficient of friction between the tires and the road is μ-0.25. If the car maintains a constant speed of 40 m/s, it will a attept to dg into the road suface. b. arrive safely at the end of the semicircle. c. tend to veer toward the center of the semicircle. d. tend to veer toward the outside of the circle. e. veer toward the center for the first quarter-circle, then veer toward the outside for the second quarter- circle
- A pickup truck negotiates an unbanked 41 m radius curve at 26 m/s. a.) Calculate the minimum coeficient of friction needed to negotiate the curve.A highway curve with a radius 900.0 ft is to be banked so that a car traveling 55.0 mph will not skid sideways even in the absence of friction. a)At what angle should the curve be banked?In 1959, Daytona Speed was added to the NASCAR racing circuit and introduced 31° banked curves for racing. This allowed stock cars to reach much higher speeds (around 200 mph) during a race. Today the steepest banked curves are found at Talladega Motor Speed Way at 33° with a turn radius of 1100 ft. The flattest track in NASCAR is Hew Hampshire Motor Speed Way with banked curves of 7° with a turn radius of 410 ft. a) Assuming no friction, what are the max speeds (in mph) without slipping toward the outer edge of the track at the Talladega and NH Motor Speedways? b) With friction (assume μs of 1.1 between the tires and the track)?
- Curved portions of highways are always banked (tilted) to prevent cars from sliding off the highway.When a highway is dry, the frictional force between the tires and the road surface may be enough to prevent sliding.When the highway is wet, however, the frictional force may be negligible, and banking is then essential. a car of mass m as it moves at a constant speed v of 20 m/s around a banked circular track of radius R = 190 m. (It is a normal car, rather than a race car, which means that any vertical force from the passing air is negligible.) If the frictional force from the track is negligible, what bank angle u prevents sliding?A 14000N car traveling at 25m/s rounds a curve of radius 200m.Find the following: A) The centripetal acceleration of the car. B) The force that maintain centripetal acceleration. C) The minimum coefficient of statistic friction between the tires and road that will allow the car to round the curve safely.On the ride "Spindletop" at the amusement park Six Flags Over Texas, people stood against the inner wall of a hollow cylinder with radius 2.9 m and axis vertical. The cylinder started to rotate, and when it reached a constant rotation rate of 0.59 rev/s, the floor on which the people were standing dropped about 0.61 m. The people remained pinned against the wall. What minimum coefficient of static friction is required if a person on the ride is not to slide downward to the new position of the floor?
- The diagram below is an official schematic of a velodrome, where track cycling takes place. The riders can goaround the track at up to 90 km/h.

Determine the coefficient of friction required to keep on the track. b. Explain why the track is banked (i.e. explain what would happen if the track were horizontal).Hi please help with the following: A car of mass M= 1400 kg traveling at 65.0 km/ hour enters a banked turn covered with ice. The road is banked at an angle theta and there is not friction between the road and the car's tires. Use g = 9.80 m/s^2 What is the radius r of the turn if theta = 20.0 degrees?
