A first approximation of friction
{"Image DocumentName": "A first approximation of friction", "Image ImageDescription": "Let\u2019s return to the circular loop problem. Let\u2019s assume that a car 550 kg car enters the circular loop going 17 m/s and exits the loop going 16.5 m/s. What is the average frictional force acting on the car?
