On a carnival ride, you stand next to a wall of a circular drum which spins around the center. When drum is spinning fast enough the floor drops away and you remain stuck to the wall and do not slide down to the floor until the drum slows down some. Assume a rider has a mass of 55.0 kg and the drum has a radius of 6.00 m. To create enough friction for the rider not to slide, the wall of the drum must provide a normal force of 558. N. What must be the linear constant speed the drum must turn with to keep the rider stuck to the wall? Select one: O a. 11.0 m/s O b. 5.52 m/s O c 71.5 m/s O d. 7.80 m/s
