A carnival ride tests your courage by putting you in a situation that would appear dangerous. A person with a mass of 75.3 kg steps into a cylindrical tube that has a radius of 4.1 m. The tube begins to rotate around its center axis. As the speed of rotation increases, the passenger feels pushed against the wall of the tube. When the tube is rotating rapidly, the floor drops out. Luckily, there is a coefficient of static friction between the passenger and the wall, which keeps them from falling. If the value of that coefficient is 0.501, then what is the minimum speed that the passenger must be moving at?
The engine of the bus applies a torque of 533 N · m to a wheel of radius 0.2 m. Since the wheel does not slip, the road must be applying a force of static friction to the wheel that produces a counter-torque. Moreover, the bus has a constant velocity, so this counter-torque balances the applied torque. What is the magnitude of the static frictional force?
A skateboarder is attempting to make a circular arc of radius r = 19 m in a parking lot. The total mass of the skateboard and skateboarder is m = 98 kg. The coefficient of static friction between the surface of the parking lot and the wheels of the skateboard is μs = 0.66. The maximum speed he can go without slipping is 11.09 m/s. He speeds up very slightly and begins to slide. The coefficient of kinetic friction is μk = 0.11. What is the new magnitude of his radial acceleration in m/s2?

A skate park is formed by two semicircles of radius R1 = 8.3 m and R2 = 1.0 m and a flat central part, as shown in the following figure. The flat part has a length L = 3.6 m. The semicircles are tangent to the horizontal in B and C and to the vertical in A and D. There is no friction in the curved parts and in the flat part the coefficient of kinetic friction is μC = 0.2. A block with mass m = 3.2 kg is dropped from A. Suppose the acceleration due to gravity is 9.8 m / s2. What is the magnitude of the velocity of the block as it passes through point B the second time?

A massless cord passing over a frictionless pulley of mass 15.0 kg and radius 55 cm connects two blocks as shown in the figure below. The 53.1° inclined plane is frictionless.

A potter's wheel-a thick stone disk of radius 0.500 m and mass 125 kg-is freely rotating at 50.0 rev/min.

Find the effective coefficient of kinetic friction between the wheel and rag.
A playground ride consists of a disk of mass M = 48 kg and radius R = 2.2 m mounted on a low-friction axle. A child of mass m = 17 kg runs at speed v = 2.7 m/s on a line tangential to the disk and jumps onto the outer edge of the disk. m V M R
A semi-cylindrical groove of radius r = 20 cm is made on a horizontal floor. An ant wants to cross the groove. A boy decides to help the ant making a bridge consisting of straight wire segments. But all the wires available are of length l = 38 cm, so the boy rigidly connects two wires at right angle and places the bridge in the groove as shown in the figure. If the ant can crawl up a wire segment at speed v = 0.5 cm/s and down a wire segment at speed 2v, in what minimum time can the ant cross the groove with the help of this bridge?
In an amusement park ride, a person with mass 70 kg stands against the wall of a cylindrical room with radius 10.3 and coefficient of friction 0.457 between the rider and the wall. The ride begins to rotate. When the ride attains a constant speed of 7.3 m/s, the floor drops down ward. The rider remains pinned against the wall. What is the magnitude of the force that the rider feels pinning him against the wall?

An object with mass M slides across a frictionless half-circular slide of radius R. The object is initially held stationary at the top of the slide. The initial height is, hi = R. The mass is released and slides down, around the bottom, and back up the other side. The radius of the slide is R = 5.79 m and the mass of the object is M = 37 kg. When the object is moving up the slide, at an angle θ = 18o from the vertical, what is the normal force on the object?
