(Solution) An automobile moves at constant speed over the crest of a hill. The driver moves in a vertical circle of radius 42.


An automobile moves at constant speed over the crest of a hill. The driver moves in a vertical circle of radius 42.6 m. At the top of the hill, she notices that she barely remains in contact with the seat.The acceleration of gravity is 9.8 m/s2.Find the speed of the vehicle.Answer in units of m/s.Mars has a mass of about 6.21 × 1023 kg,and its moon Phobos has a mass of about1 × 1016 kg.If the magnitude of the gravitational force between the two bodies is 4.19 × 1015 N,how far apart are Mars and Phobos? The value of the universal gravitational constant is 6.673 × 10?11 N · m2/kg2.Answer in units of m. A 3055 kg car rounds a circular turn of radius21 m. The road is flat and the coefficient of friction between tires and road is 0.55.The acceleration of gravity is 9.8 m/s2.How fast can the car go without skidding?Answer in units of m/s.
