A carnival ride has people stand inside a vertical cylinder with their backs to the wall. The cylinder starts spinning counterclockwise and the riders find that they are “stuck” to the wall and don’t slide down, even when the floor is removed. The ride has a radius of r. The person has a mass of m and is moving with a constant speed of v. The coefficient of static friction between the person and the wall is μs , and kinetic friction μk. The person is only touching the wall, not touching the floor. a) Draw a free body diagram for the person when they are on the left-hand side, as shown. Clearly label all forces. Use the notation used in class. b) What is the magnitude and direction of the acceleration of the person? Give your answer in terms of variables only (r, v, m, μs, μk, and g) c) What is the magnitude of the normal force of the wall on the person? Solve this problem using Newton’s 2nd Law. Show all your work. Give your answer in terms of variables only (r, v, m, μs, μk, and g
