Once the zip line has been completed, you walk up a path that takes you to an outcropping. A short bridge leads you to a scenic platform overhanging a drop. As soon as everyone in your group has gotten on the platform, your guide closes a gate and pushes a switch. You realize that the platform is attached to a pivot by a 10 m arm. The platform (12 m × 12 m) swings around to land against another landing 200° around the circle from your initial position. The swing takes 1 minute. Take the swing as travelling clockwise relative to the viewer. a) What is the average angular velocity of the platform? b. What is the distance travelled by a person in the middle of the platform during the swing? c. What is the difference between the tangential velocity of a person standing closest to the outer edge of the platform compared to that of the person standing closest to the pivot?
