5. A force of 10 N applied to one end of a cord keeps an object tied to the other end moving at a speed of 2.0 m/s in a horizontal circle of radius 3.0 m. What is the mass of the object? A 1200-kg car traveling at a constant speed of 9.0 m/s turns at an intersection. The car follows a horizontal circular path with a radius of 25 m to point P. 1200-kg |V=9.0 m/s car Car's path r=25 Ice A D B 6. What is the magnitude of the centripetal force acting on the car as it travels around the circular path? 7. What must the minimum coefficient of friction between the tires and road be in order for the car to make the turn safely, without slipping? 8. At point P, the car hits an area of ice and loses all frictional force on its tires. Which path does the car follow on
