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?

On the International Space Station an object with mass m = 440 g is attached to a massless string of length L = 0.61 m. The string can handle a tension of T = 5.8 N before breaking. The object undergoes uniform circular motion, being spun around by the string horizontally.What is the maximum speed v the mass can have before the string breaks? Give your answer in units of m/s.
In deep space, an astronaut is whipping a heavy tool around in a circle by a taut cable. The cable is 1 meter long (from the astronaut's fist to the tool), and the tool makes a full trip around the circle in half a second as it moves with constant speed. The mass of the tool is 10 kg. What is the tension in the cable?
On the International Space Station an object with mass m = 290 g is attached to a massless string L = 0.99 m. The string can handle a tension of T = 6.8 N before breaking. The object undergoes uniform circular motion, being spun around by the string horizontally. What is the maximum speed v the mass can have before the string breaks? Give your answer in units of m/s.
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?
At an amusement park there is a ride in which cylindrically shaped chambers spin around a central axis. People sit in seats facing the axis, their backs against the outer wall. At one instant the outer wall moves at a speed of 3.16 m/s, and an 85.3-kg person feels a 546-N force pressing against his back. What is the radius of a chamber?
You are in a carnival ride that consists of a circular room that spins around its center. You stand against the wall at the edge of the room. The room spins at a constant rate of one revolution every 5 seconds, and the room has a radius of 5 m. Your mass is 70 kg. After the room reaches it final speed, the floor drops out from beneath you, yet you remain stuck to the wall. What is the magnitude of the normal force exerted on you by the wall, and at what rate (power) does the normal force perform work on you? (Please explain the power that the normal force does work in detail.)
A skateboarder is attempting to make a circular arc of radius r = 11 m in a parking lot. The total mass of the skateboard and skateboarder is m = 86 kg. The coefficient of static friction between the surface of the parking lot and the wheels of the skateboard is μs = 0.59 . He speeds up very slightly and begins to slide. The coefficient of kinetic friction is μk = 0.21. What is the new magnitude of his radial acceleration in m/s2?
You are swinging a tennis ball attached to a 55 cm long cord, swinging the tennis ball in a circle. As you swing the tennis ball, the force of tension in the cord keeps the tennis ball in a circular path. The mass of the tennis ball is 0.25 kg, and as it swings around, speed of the tennis ball is 3.8 m/s. What is the force of tension in the cord? (the unit of force is the 'Newton' )
