Question
The options are, one, two, three, four, five, six, downwards, horizontally towards the wall, upwards, horizontally away from the wall, does, does not, should, should not, zero, mv^2/r, Bob's weight, the static friction force, equal to, less than, greater than,
Bob, along with a few other people, are riding the Rotor, which is (or at (east was) a popular amusement park ride. When the ride begins, riders enter the Rotor (a Large, hollowed-out cylinder with vertical walls), and Line up with their backs against the wall. The Rotor begins to rotate, causing the riders to be pressed up against the wall as they execute circular motion around the central axis of the cylinder. When the Rotor reaches a certain (constant) speed, the floor is removed, causing the riders to apparantly hang freely on the walls of the cylinder. Only static friction actually prevents the riders from falling. For this particular ride, the radius of the cylinder is 2.80 m. Bob has a mass of 75.2 kg and is wearing a raincoat, such that the coefficient of static friction between his raincoat and the wall is 0.560. After the Rotor reaches its constant speed and the floor is removed, the force diagram showing forces acting on Bob consists of______ forces, including a gravitational force directed ________, a normal force directed_________, and a static friction force directed __________ . The centrifugal force that seems to push Bob to the outside of the circle ______ really exist, and _______be included in the force diagram. Applying Newton?s Second Law to Bob yields two equations, one equating the static friction force to ______, and the other equating the normal force to _______ . Applying the condition that static friction should be _______ Mu N, we find that the Rotors speed v must be [ ] [ ] m/s if Bob is to not slide down the wall when the floor is removed. Report your answer to 3 significant digits.Explanation / Answer
