To test the performance of its tires, a car travels along a perfectly flat (no banking) circular track of radius 101 m. The car increases its speed at uniform rate of 3.56 m/s^2 until the tires start to skid. If the tires start to skid when the car reaches a speed of 16.9 m/s what is the coefficient of static friction between the tires and the road?

1. An 800 kg car travels around the edge of a circular track of radius 400 m. At one point, the car accelerates around the track, increasing its speed from 40 m/s to 60 m/s over the course of 5 s. At the instant that the car reaches 50 m/s find (a) its angular velocity (b) its radial acceleration, (c) the centripetal force acting on the car, (d) the tangential acceleration of the car, and (e) the magnitude of the...

A car travels at constant speed around a corner. The cars speed is 35 m/s and the radius of the circle is 0.25 km. The coefficient of static friction between the tires and the road is 0.7. What is the frictional force needed for the car to make the turn? What is the maximum force the static friction can produce? Does the car stay on the road? The car is in motion so why is the static friction important?

A car travels at a speed of 21 m/s around a curve of 27 m. m = 1500 kg (i) What is the net centripetal force needed to keep the car from skidding sideways? (ii) Were there no friction between the car’s tires and the road, what centripetal force would be provided just by banking the road at 29o? (iii) Now, suppose a friction force is also present and prevents the car from skidding. Calculate the magnitude of the normal...
