problem 1: A bump in a road causes a car moving at 32 m/s to lose contact with the road as it travels over it. If the car has a mass of 1200 kg, then what is the radius of the bump?

problem 2: A 75 kg fighter pilot is pulling out of a steep dive which is similar to the bottom of a vertical circle. If the pilot feels a g-force of 8.5 gs and is travelling at 300 m/s, find out the radius of the circle?

problem 3: Find out the co-efficient of friction of an unbanked corner if a truck can navigate the 25.0 m radius corner at a maximum speed of 18 m/s?

problem 4: Road designers want to make an exit ramp with a radius of 215m. They want cars to be able to exit at 55 km/h. at what angle do they require to bank the curve?
