Ex. 64: A car can be driven on a flat circular road of radius r at a maximum speed v without skidding. The same car is now driven on another flat circular road of radius 2r on which the coefficient of friction between the tyres and the road is the same as on the first road. What is the maximum speed of the car on the second road such that it does not skid ?

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 jet dives vertically at a speed v = 174 m/s, before pulling out of the dive along a circular arc. The pilot can survive an acceleration of a = 8.6 g. His mass is m = 91 kg. What is the minimum radius of the circular arc, in meters, that the pilot can make without injury? (Watch you sigfigs) I understand how to calculate this answer, but I need help determining the correct number of sig figs for the answer.
A 2.35 kg water bucket is swung in a full circle of radius 0.824 m just fast enough so that the water doesn't fall out at the top (meaning n = 0 there). What is the speed of the water at the top? (Unit = m/s) Enter
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.
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?
