A potter's wheel is rotating around a vertical axis through its center at a frequency of 1.8 rev/s . The wheel can be considered a uniform disk of mass 5.1 kg and diameter 0.40 m . The potter then throws a 2.5-kg chunk of clay, approximately shaped as a flat disk of radius 7.5 cm , onto the center of the rotating wheel. |
Part A What is the frequency of the wheel after the clay sticks to it? Express your answer using two significant figures. |

A potter is shaping a bowl on a potter's wheel rotating at constant angular speed. The friction force between her hands and the clay is 1.6 N total. a) How large is her torque on the wheel, if the diameter of the bowl is 13 cm ? b) How long would it take for the potter's wheel to stop if the only torque acting on it is due to the potter's hand? The initial angular velocity of the wheel is...

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. The potter can stop the wheel in 6.00 s by pressing a wet rag against the rim and exerting a radially inward force of 71.0 N. Find the effective coefficient of kinetic friction between the wheel and rag.

A potter's wheel having a radius of 0.500 m and mass 45.0 kg is rotating freely at 50.0 rev/min in a clockwise direction. The potter can stop the wheel by pressing a wet rag against the outside rim of the wheel and exerting a radially inward force of 70.0 N. Since this force is in the radial direction, it alone cannot cause the wheel to slow its spinning. What can happen, however, is that a normal force can result from...

A thin, flat disk rotates at 12.9 rev/min around a vertical axis at its center. (a) What is its angular speed in radians per second? What is the linear speed (in centimeter per second) of a point on the disk (b)29.2 cm and (c)5.94 cm from the rotation axis?
A uniform disk with mass M and radius R is rotating about an axis through its center-of-mass.
A uniform disk with mass M and radius R is rotating about an axis through its center-of-mass. The axis is perpendicular to the disk. The moment of inertial for the disk with a central axis is I MR2. Two non-rotating smaller disks, each with mass M2 and radius R/4, are glued on the original disk as shown in the figure. (a) Show that the ratio of the moments of inertia is given by I'/I = 35/16, where I' is the moment...
A turntable has a radius of 0.80 m and a moment of inertia of 2.0 kg m2. The turntable is rotating with an angular velocity of 1.5 rad/s about a vertical axis though its center on frictionless bearings.
A turntable has a radius of 0.80 m and a moment of inertia of 2.0 kg m2. The turntable is rotating with an angular velocity of 1.5 rad/s about a vertical axis though its center on frictionless bearings. A very small 0.40-kg ball is projected horizontally toward the turntable axis with a velocity of 3.0 m/s. The ball is caught by a very small and very light cup-shaped mechanism on the rim of the turntable (see figure). a) What is the...
