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?
A skateboarder is attempting to make a circular arc of radius r = 14 m in a parking lot. The total mass of the skateboard and skateboarder is m = 89 kg. The coefficient of static friction between the surface of the parking lot and the wheels of the skateboard is μs = 0.59 .
What is the maximum speed, in meters per second, he can travel through the arc without slipping?
An air puck of mass m1 = 0.25 kg is tied to a siring and allowed to revolve in a circle of radius R = 1.0 m on a frictionless horizontal table. The other end of the string passes through a hole in the center of the table, and a mass of m2 = 1.0 kg is tied to it (Fig. P7.27). The suspended mass remains in equilibrium while the puck on the tabletop revolves, (a) What is the tension in the string? (b) What is the horizontal force acting on the puck? (c) What is the speed of the puck?
