Thanks for asking ..
hi. i am stuck. please help with all of these. thank you A potter's wheel, with...
A potter's wheel, with rotational inertia 21 kg-m2. is spinning freely at 40 rpm. The potter drops a lump of clay onto the wheel, where it sticks a distance 1.2 m from the rotational axis. If the subsequent angular speed of the wheel and clay is 32 rpm what is the mass of the clay? 4.0 kg 4.3 kg 3.6 kg 2.4 kg 3.1 kg
A potter's wheel, with rotational inertia 24 kg*m^2 is spinning freely at 40 rpm The potter drops a lump of clay onto the wheel, where it sticks a distance 1.2 m from the rotational axis. If the subsequent angular speed of the wheel and clay is 32 rpm what is the mass of the clay?
A potter's wheel is rotating around a vertical axis through its center at a frequency of 1.7 rev/s. The wheel can be considered a uniform disk of mass 5.8 kg and diameter 0.40 m. The potter then throws a 3.1 kg chunk of clay that is shaped like a flat disk of radius 8.0 cm, onto the center of the rotating wheel. What is the frequency of the wheel after the clay sticks to it?
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 is rotating around a vertical axis through its center at a frequency of 2.0 rev/s. The wheel can be considered a uniform disk of mass 4.9 kg and diameter 0.40m. The potter then throws a 2.7 kg chucnk of clay, approximately shaped as a flat disk of radius 8.0 cm, onto the center of the rotating wheel. What is the frequency of the wheel after the clay sticks to it? Ignore friction/.
can someone help me solve 5-7 5. Two particles of mass 1 kg each are attached to a massless rod a distance of 1 m and 2 m respectively from the axis of rotation. The axis of rotation is perpendicular to the rod. The angular speed of the system is I rad/s. What is the magnitude of the angular momentum of the system (in SI units)? 1kg - 1kg 1 m 2 m Lamur 3 A1 B. 4 1.1.2 Homes...

Part B What is the centripetal acceleration of a small lump of clay on the rim of the wheel? Part C What is the linear speed if the period of rotation is doubled? Part D What is the centripetal acceleration if the...
A potter is shaping a bowl on a potter's wheel rotating at constant angular velocity of 1.3 rev/s (Figure 1). 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 9.0 cm? Express your answer to two significant figures and include the appropriate units. b. How long would it take for the potter's wheel to stop if the only torque acting...
(Figure 1) shows the angular position of a potter's wheel. Part A What is the angular displacement of the wheel between t = 5 s and t = 15 s? Express your answer in radians.Part B What is the angular velocity of the wheel at 15 s? Express your answer in radians per second.Part C What is the maximum speed of a point on the outside of the wheel 15 cm from the axle? Express your answer with the appropriate...
