30 m 5. The standard test to determine the maximum lateral acceleration of a car is to drive it around a 70 m - diameter circle painted on a level asphalt surface. The driver slowly increases the vehicle speed until he is no longer able to keep both wheel pairs straddling the line. If this maximum speed is 16 m/s for a 1500-kg car, determine the coefficient of friction between the pavement and the car tires. (10 marks)

A sports car is advertised to have a maximum cornering acceleration of 0.85 g. What is the maximum speed that the car can go around a curve with a 100-m radius? What is its maximum speed for a 50-m radius curve? If wet pavement reduces its maximum cornering acceleration to 0.6g, what do the answers to (a) and (b) become?

a. Calculate the maximum safe speed for a 2 ton car traveling around a curve with a radius of 150 yards given a force of friction of 650 N. Provide your answer in m/s and mph. At the maximum safe speed, what is the centripetal acceleration of the car? Given that the force of friction remains 650N, if the car is traveling at twice the maximum safe speed around a curve with a radius that is twice as large, will...

A civil engineer wishes to redesign the curved roadway in the figure in such a way that a car will not have to rely on friction to round the curve without skidding. In other words, a car moving at the designated speed can negotiate the curve even when the road is covered with ice. Such a ramp is usually banked, which means that the roadway is tilted toward the inside of the curve. Suppose the designated speed for the road...
