Bob is driving with constant speed in a curved path with radius r = 50 m. If the coefficient of static friction between his tires and the road is 0.5, what is the maximum speed he can have without skidding?

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?

A circular automobile racetrack is banked at an angle θ, to the horizontal, such that no friction between the road and tires is required when a car travels at 30.0 m/s. The radius of the track is 400 m. What is the angle θ?

It was a dark and stormy night in Winona, Minnesota. A driver advances alongan icy road - assume there is no friction between the tires and the road - must ne-gotiate a turn for which the road traces out an arc of a circle of radius 321 m. Theroad is banked at an angle of 5.2 . What is the speed with which she must take the curve to avoid sliding?

A car rounds a level (unbanked) curve with a radius of 95 m without skidding at a speed of 25 m/s. What is the smallest possible coefficient of friction between the tires and the ground? Is the friction static or kinetic? Include a force (or free body) diagram of the situation.

In a recent study of how mice negotiate turns, the mice ran BIO around a circular 90° turn on a track with a radius of 0.15 m. The maximum speed measured for a mouse (mass = 18.5 g) running around this turn was 1.29 m/s. What is the minimum coefficient of friction between the track and the mouse's feet that would allow a turn at this speed?

A car is driving along a circular track with diameter d = 0.59km at a constant speed of v = 21.2 m/s.  Write an expression and find the value for the minimum coefficient of friction between the cars tires and road required in order to keep the car going in a circle in terms of the given parameters.

The curved section of a horizontal highway is a circular unbanked arc of radius 520 m.  If the coefficient of static friction between this roadway and typical tires is 0.30, what would be the maximum safe driving speed for this horizontal curved section of highway?

A hang glider and its pilot have a total mass equal to 134 kg. While executing a 360° turn, the glider moves in a circle with a 9 m radius. The glider's speed is 15 m/s. (Assume the glider turns along the horizontal plane.) (a) What is the net force on the hang glider?(b) What is the acceleration?

A 834 kg automobile is moving at a maximum speed of 33 m/s on a level circular track of radius 362 m. What is the coefficient of friction?
