In a classic carnival ride, patrons stand against the wall in a cylindrically shaped room. once the room gets spinning fast enough, the floor drops from the bottom of the room! friction between the walls of the room and the people on the ride make them the "stick" to the wall so they do not slide down. in one ride, the radius of the cylindrical room is r = 7.4 m and the room spins with a frequency of 21.1 revolutions per minute. 1) what is the speed of a person "stuck" to the wall?

Large pool of blood is found in the center of a room with a tile floor. there are zigzagging, arc-like bloodstains on one wall with drops of blood 1–4 mm in size and drips running down the wall. on an adjacent wall, there is a neat horizontal line of 1–4 mm drops of blood stretching across the length of the wall. from the center of the room, stretching to the door, there is a line of 4–6 mm blood drops that are slightly elongated. based on this evidence, which is the most likely seque

In a classic carnival ride, patrons stand against the wall in a cylindrically shaped room. once the room gets spinning fast enough, the floor drops from the bottom of the room! friction between the walls of the room and the people on the ride make them the "stick" to the wall so they do not slide down. in one ride, the radius of the cylindrical room is r = 6.3 m and the room spins with a frequency of 23.5 revolutions per minute. 1. speed of the rider. i used circumfrence * revolutions/ 60 to get 15.5. (already known to be correct) 2. what is the normal force? 3. what is the minimum coefficient of friction needed between the wall and the person? 4)if a new person with mass 92 kg rides the ride, what minimum coefficient of friction between the wall and the person would be needed? 6) to be safe, the engineers making the ride want to be sure the normal force does not exceed 1.7 times each persons weight - and therefore adjust the frequency of revolution accordingly. what is the minimum coefficient of friction now needed?
