A car rounds a curve that is banked inward. The radius of curvature of the road is R = 142 m, the banking angle is θ = 30°, and the coefficient of static friction is μs = 0.32. Find the minimum speed that the car can have without slipping. I got 36.5196 m/s, which isn't correct.

A curve with a 130 m radius on a level road is banked at the correct angle for a speed of 20 m/s. If an automobile rounds this curve at 30 m/s, what is the minimum coefficient of static friction between tires and road needed to prevent skidding?

Q5: A flatbed truck starts from rest on a road whose constant radius of curvature is 30 m and whose bank angle is 1°. If the constant forward acceleration of the truck is 2 m/s, determine the time t after the start of motion at which the crate on the bed begins to slide. The coefficient of static friction between the crate and truck bed is -0.3, and the truck motion occurs in a horizontal plane. (5.58 s 10°

Suppose that a particular highway offramp with a curve radius of 56 m is banked at 10˚ and was originally designed to include a coefficient of static friction of 0.25 between tires and road. If the DoT wants to repost the speed limit so that the curve is correctly banked when including a friction coefficient of only 0.1, what new speed should be posted?
Banked curves are designed so that the radial component of the normal force on the car rounding
Banked curves are designed so that the radial component of the normal force on the car rounding the curve provides the centripetal force required to execute uniform clrcular motion and safely negotlate the curve. A car rounds a banked curve with banking angle θ-27.1° and radius of curvature 157 m. (a) It the coefficient of static friction between the car's tires and the road is -0.316, what is the range ot speeds for which the car can safely negotiate the turn...

A car is travelling at a flat circular track of radius 25 m and tries to go around at 40 m/sec. a) What should the coefficient of static friction be so the car won’t skid? b) Assume the same car is now travelling at a banked circular track at angle 25o , r=25 m and with same speed. What’s the value of the coefficient of static friction in order for the car not to slide down? c) What would the...

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 = 270 m and bank angle θ, where the coefficient of static friction between...
