A 2300 kg car moving at an initial speed of 25 m/s along a horizontal road skids to a stop in 50 m. (Note: When stopping without skidding and using conventional brakes, 100 percent of the kinetic energy is dissipated by friction within the brakes. With regenerative braking, such as that used in hybrid vehicles, only 70 percent of the kinetic energy is dissipated.)

A curve of radius 20 m is banked so that a 1100 kg car traveling at 30 km/h can round it even if the road is so icy that the coefficient of static friction is approximately zero. The acceleration of gravity is 9.81 m/s 2 . Find the minimum speed at which a car can travel around this curve without skidding if the coefficient of static friction between the road and the tires is 0.3. Answer in units of m/s.

The Daytona 500 stock car race is held on a track that is approximately 2.5 mi long, and the turns are banked at an angle of 31°. It is currently possible for cars to travel through the turns at a speed of about 164 mi/h. Assuming these cars are on the verge of slipping into the outer wall of the racetrack, find the coefficient of static friction between the tires and the track. (Assume that the track is circular.)

You are driving your car uphill along a straight road. Suddenly, see a car cross a red light and enter the intersection, just ahead of you. Immediately apply your brakes and skid in a straight line to stop, leaving a mark of 100 ft long by sliding. A policeman observes the whole incident, gives a ticket to the driver of the car for passing a red light. It also gives a ticket to you for exceeding the 30 mph speed...
