I just need Question 4
3) A car is driven around one curved road, whose radius is 320 m and then another whose radius is 960 m. In both cases, the speed is 28 m/s. Compare the centripetal acceleration for both turns. 4) Compare the maximum speeds at which a car can safely negotiate an unbanked turn (radius 50.0 m) under normal conditions (Lis 09) and icy condition (M.-0.1).

1) A car with mass m = 1000 kg is traveling around a circular curve of radius r = 990 m when it begins to rain. The coefficients of static friction between the road and tires is μd = 0.66 when dry and μw = 0.26 when wet. a) Write an expression for the maximum magnitude of the force of static friction Ff acting on the car if μs is the coefficient of friction. b) What is the maximum tangential...

009 (part 1 of 2) 10.0 points A civil engineer is asked to design a curved section of roadway that meets the following conditions: With ice on the road, when the coefficient of static friction between the road and rubber is 0.24, a car at rest must not slide into the ditch and a car traveling less than 70 km/h must not skid to the outside of the curve. The acceleration of gravity is 9.81 m/s2. At what angle should...
