What is the maximum speed with which a 1200-kgkg car can round a turn of radius 90.0 mm on a flat road if the coefficient of static friction between tires and road is 0.50?

A 2000 kg car is driving at a constant speed of 34.9 m/s takes a curve with a 80 m radius. The road is not banked (level road). What is the minimum value of the coefficient of static friction between the tires and the road so that the car can take this curve without slipping? Round your final answer to 1 decimal place. Side note: The speed's value is, in the range of 40 mph to 80 mph, given randomly in the question. If the coefficient of static friction is larger than 1, the car would slip. It is unrealistic to have that high the coefficient of friction in real life. Don't over-speed!

A sample of blood is placed in a centrifuge of radius 20.0 cm. The mass of a red blood cell is 3.0 x 1010 kg, and the magnitude of the force acting on it as it settles out of the plasma is 4.0 x 10-11 N. At how many revolutions per second should the centrifuge be operated? rev/s Need Help? Read It

A car going around an unbanked curve is found to be able to take the curve with maximum speed “v.” You would like to triple the maximum speed the car can take the curve. To do this, you could:     triple the coefficient of friction between the car and the road;     decrease the radius of the road by a factor of three     increase the radius of the road by a factor of nine     decrease the coefficient of friction between the car and the road by a factor of nine;

At what maximum speed can a car negotiate a turn on a wet road with coefficient of static friction 0.200 without sliding out of control? The radius of the turn is 27.5 m.

Engineers are designing a curved section of a highway to fit into a specific area. The curve has radius 121 m and is banked at an angle such that a car can travel around the curve at 28.7 m/s and stay on the road without the aid of a frictional force. Calculate the required banking angle (as measured above the horizontal). 0 =

If 0.5 kg-ball is swung in the horizontal direction, what force must a person exert on a string attached to make it revolve in a horizontal circle of radius 2.5 m. The ball makes 420 rpm.

If the curve on the road has a bank angle of 18 degrees and the radius of curvature is 225m. a) what is the maximum speed you can go if the coefficient of friction between the tires and the road is 0.3? Your car is 1500kg. b)What is the minimum speed you can go without sliding?

The posted speed limit for a flat (unbanked) curve of radius 45m is 45mph. What is the required coefficient of static friction between the road and car tires for this turn to be negotiated safely?
