The drive motor is shifted to turn the carousel at a higher constant rate of rotation, and the piece of luggage is bumped to another position, 7.94 meter from the axis of rotation. Now going around once in every 30.9 s, the bag is on the verge of slipping. Find the coefficient of static friction exerted by carousel on the bag.
