A solid cylinder (LaTeX: I\:=\frac{\:1}{2}MR^2 I = 1 2 M R 2 ) potter's wheel is a thick stone of radius 7 m with mass 5 kg. It freely rotates at 9 radian per second. The potter press a wet rag against the rim and exert a radially inward force of 10 N. If the coefficient of kinetic friction between the rag and the wheel is 0.6, find the time needed for the wheel to stop in seconds.

- A very light rope is wrapped around a wheel of radius R = 2.0 meters and does not slip. The wheel is mounted with frictionless bearings on an axle through its center. A block of mass 14 kg is suspended from the end of the rope. When the system is released from rest it is observed that the block descends 10 meters in 2.0 seconds.

The pulley, called a sheave, is a solid cylinder of radius 0.700 m turning on a horizontal axle. The cable does not slip on the sheave. A number n of people, each of mass 80.0 kg, are riding in the elevator car, moving upward at 3.00 m/s and approaching the floor where the car should stop. As an energy-conservation measure, a computer disconnects the elevator motor at just the right moment so that the sheave–car– counterweight system then coasts freely without friction and comes to rest at the floor desired. There it is caught by a simple latch rather than by a massive brake. (a) Determine the distance d the car coasts upward as a function of n. Evaluate the distance for (b) n = 2, (c) n = 12, and (d) n = 0. (e) For what integer values of n does the expression in part (a) apply?

At the bottom of the tank, a rigid rod of length L is pinned to the frictionless floor and the other end is connected to a small object of mass m with a rocket nozzle on it. The rocket will exert a constant thrust force of magnitude F, directed in the tangential direction. The object will start from rest, rotating about a circle in the horizontal plane when the rocket motor is turned on. Since it is under water, the object experiences a drag force that depends linearly on the objects velocity D=-bỷ where b is a constant and v is the object's velocity vector (the minus sign just means that the drag force points in the direction OPPOSITE the object's velocity). a) Draw a complete FBD of the object while it is speeding up.

- A bicycle wheel is mounted on a fixed, frictionless axle, with a light string wound around its rim. The wheel has moment of inertia I=kmr2, where m is its mass, r is its radius, and k is a dimensionless constant between zero and one. The wheel is rotating counterclockwise with angular speed ω0, when at time t=0 someone starts pulling the string with a force of magnitude F. Assume that the string does not slip on the wheel. Suppose that after a certain time tL, the string has been pulled through a distance L. What is the final rotational speed ωfinal of the wheel? Express your answer in terms of L, F, I, and ω0.arrow_forwardAn air puck of mass m1 = 0.16 kg is tied to a string and allowed to revolve in a circle of radius R = 1.1 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 = 1.5 kg is tied to it (see the figure below). The suspended mass remains in equilibrium while the puck on the tabletop revolves. (a) What is the tension in the string (in N)? (b) What is the horizontal force acting on the puck (in N)? (c) What is the speed of the puck (in m/s)? m/sarrow_forwardA block with mass m1 = 3.00 kg sits on a horizontal table and is attached to a rope. The rope then passes over a MASSIVE pulley this time and is attached to a block of mass m2 = 2.00 kg, which hangs vertically. The coefficient of kinetic friction of the interface between the table and m1 is 0.1. You may assume the pulley section is a disk with a mass of 2 kg. We will keep the pulley frictionless for brevity. Find the acceleration of the blocks using your choice of either Newton’s Laws or the energy conservation method.arrow_forward
