As shown in Fig. 3, a 5.00 kg roller coaster starts from rest at point A and slides down the frictionless loop-to-loop. (a) How fast is this roller coaster moving at point B7 (b) What are the magnitude and direction of the normal force on the roller coaster at B7 If the beginning segment of the track is rough with coefficient of kinetic friction 0.600, (c) how fast is this roller coaster moving at point C, and (d) what are the magnitude and direction of the normal force on it at C? (e) if the coefficient of kinetic friction of the beginning segment is increased so that the particle can barely complete the circular motion without falling, what is the coefficient of the kinetic friction? 65.0 m Beginning segment (20.0 m) a 20.0⁹ Fig. 3 *** R=20.0 m
