4. A Ferris wheel of radius 15 m turns clockwise as shown. A man of mass 70 kg stands on a scale in the Ferris wheel car without slipping. At the time shown, the man is moving down at 4 m/s but speeding up at a rate of 1.5 m/s?. a. Draw the free body diagram showing the forces on the man. b. What is the static friction force acting on the man? c. What does the scale read at this time? d. Now assume that the man's shoes just start slipping on the scale at this time. What is the coefficient of static friction between the man shoes and the scale?
