A carnival ride has people stand inside a vertical cylinder with theirbacks to the wall. The cylinder starts spinning counterclockwise and theriders find that they are “stuck” to the wall and don’t slide down, evenwhen the floor is removed.The ride has a radius of r. The person has a mass of m and is movingwith a constant speed of v. The coefficient of static friction between theperson and the wall is μs , and kinetic friction μk. The person is onlytouching the wall, not touching the floor. 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)d) What is the smallest speed v for which the person will not slide down the wall?Solve this problem using Newton’s 2nd Law. Show all your work.Give your answer in terms of variables only (r, m, μs, μk, and g)e) Suppose that the ride spun clockwise instead of counterclockwise, but the speed was thesame.…

"plastered" against the wall. Suppose the radius of the room is 3.91 m and the speed of the wall is 13.9 m/s when the floor falls away. The source of the centripetal force on the riders is the normal force provided by the wall. (a) How much centripetal force acts on a 54.5 kg rider? (b) What is the minimum coefficient of static friction that must exist between the rider's back and the wall, if the rider is to remain in place when the floor drops away
A flat belt is used to transmit a couple from pulley to pulley B. The radius of each pulley is 60 mm, and a force of magnitude P = 900 N is applied as shown to the axle of pulley A. Knowing that the coefficient of static friction is 0.35, determine (a) the larg- est couple that can be transmitted, (b) the corresponding maximum value of the tension in the belt. 0000 240 mm BO
A speedboat with a mass of 505 kg (including the driver) is tethered to a fixed buoy by a strong 29.7 m cable. The boat's ownerloves high speed, but does not really want to go anywhere.
