The angular position of the 80-kg person riding a rotor is described by 0 (1) = ln(21+ 1). The radius of the rotor is 5 m. Answer the following questions at 1 second. Show all intermediate steps. t (a) [2 pts] What is the angular speed of the person? (b) [2 pts] What is the angular acceleration of the person? (c) [3 pts] What is the total friction force in N on the person? (d) [3 pts] What is the normal force in N on the person? (e) [3 pts] What is the least static friction coefficient between the person and the wall to avoid slipping? (f) [2 pt] Is the rotor slowing down or speeding up? Why? R axis of rotation
