positivephysics A student is riding a bike and wants to brake as quickly as possible! As a wise physics student, she knows that she should press the brakes as much as she can WITHOUT causing the tires to skid. She also knows that the combined mass of the her and the bicycle is90kg, the coefficient of static friction between the road and the tires is 0.67, the coefficient of kinetic friction is 0.56 and that she is experiencing a 30N drag. Answer each of the following questions for the case in which the bicyclist is slowing down as quickly as possible. How many forces are acting on the bicyclist? 4 What direction is the friction? left Is the friction static or kinetic? static What is the magnitude of the friction? 59 N What is the magnitude of the net force on the bicyclist? N What is the magnitude of bicyclist's acceleration? m/s2 Is it possible for the bicyclist to slow down with an acceleration of 9m/s2 in this case? Hint!
