- An air puck of mass ml is tied to a string and allowed to revolve in a circle of radius R 5 1.0 m on a frietionless horizontal table. The other end of the string passes through a hole in the center of the table, and a mass of m2 is tied to it. The suspended mass remains in equilibrium while the puck on the tabletop revolves.

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?arrow_forwardOf the two frictionless inclined planes with slopes of 30 ° and 53 °, masses m1 = 4kg on the first and m2 = 2kg on the second.

Find the accelerations (the linear accelerations of the masses and the angular acceleration of the pulley) and the stresses in the rope.

- Problem 1: Two uniform solid spheres, each with mass M = 0.80-kg and radius R = 0.080- m, are connected by a short, light rod that is along a diameter of each sphere and are at rest on a horizontal tabletop. A spring with force constant k 160 N has one end m attached to the wall and the other end attached to a frictionless ring that passes over the rod at the center of mass of the spheres, which is midway between the centers of the two spheres.
