A car with a mass of 1090 kg is traveling in a mountainous area with a constant speed of 75.4 km/h. The road is horizontal and flat at point A, horizontal and curved at points B and C.

The radii of curvatures at B and C are: rB = 135 m and rC = 100 m. Calculate the normal force exerted by the road on the car at point A.

Now calculate the normal force exerted by the road on the car at point B.

And finally calculate the normal force exerted by the road on the car at point C.

As a car traveling to the right passes you, you look at your watch and measure the speed of the car. The watch reads 16.0 seconds. The speed of the car is 20 m/s. The car also starts to accelerate at a constant rate when it passes you. 15 meters down the road to the right, the car is measured to be traveling at 10 m/s to the right. What kind of a problem is this? A force, non-constant acceleration...

Traveling at 40.2 m/s, a driver applies the brakes to his fast-moving car and skids out of control on a wet concrete horizontal road. The 2000 kg car is headed directly toward a student waiting to catch a bus to campus who is standing 58.0 m down the road. Luckily, Superman is flying overhead and surveys the situation. Knowing that the coefficient of kinetic friction between rubber and rough wet concrete is .800, he determines that friction alone will not...
