Maria is racing her bike down the cobblestone sidewalk. She is riding at a constant velocity of 10.2m/s. Suddenly a group of people step out in front of her. They are 6 meters in front and she needs to stop. The coefficient of friction between the ground and Maria's tire is 0.35. The mass of her + her bike is 130kg. She slams the brakes with 800N of force. Will she be able to stop in time? Or will she run over the people?
