IP A potter's wheel of radius 6.5 cm rotates with a period of 0.70 s .
Part A
What is the linear speed of a small lump of clay on the rim of the wheel?
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 period of rotation is doubled?
Part A & B
Radius of the wheel = R = 6.5 cm = 0.065 m
Time period of rotation = T = 0.7 sec
Angular speed of the wheel =
= 8.976 rad/s
Linear speed of a lump of clay on the rim of the wheel = V
V = 0.583 m/s
Centripetal acceleration of the lump of clay = a
a = 5.24 m/s2
Part C & D
Time period of rotation is doubled.
Radius of the wheel = R = 6.5 cm = 0.065 m
Time period of rotation = T = 2 x 0.7 sec = 1.4 sec
Angular speed of the wheel =
= 4.488 rad/s
Linear speed of a lump of clay on the rim of the wheel = V
V = 0.292 m/s
Centripetal acceleration of the lump of clay = a
a = 1.31 m/s2
A) Linear speed of a lump of clay on the rim of the wheel = 0.583 m/s
B) Centripetal acceleration of the lump of clay = 5.24 m/s2
C) Linear speed if the period of rotation is doubled = 0.292 m/s
D) Centripetal acceleration if the period of rotation is doubled = 1.31 m/s2

A potter's wheel rotating at 235 rev/min is switched off and rotates through 78.5 revolutions prior to coming to rest. What is the constant angular acceleration of the potter's wheel during this interval? (Assume the positive direction to be the direction of rotation of the wheel. Indicate the direction with the sign of your answer.) rad/s2 Need Help?Wateh Read It
a bicycle wheel with a radius of .62 m rotates with an angular speed of 25 rad/s about its axis, which is at rest. what is the linear speed of a point on the rim of the wheel
hi. i am stuck. please help with all of these. thank you 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? 3.1 kg 4.3 kg 2.4 kg 4.0 kg 3.6 kg The simple harmonic...
A London eye fears wheel in London has a diameter of 120 m the wheel rotates at 26 cm/s the slow speed is so that the passengers can get off and on without it stopping. a) what is the period of revolution, i.e. how long does it take for it to go around once b) what is the magnitude of the passenger's centripital acceleration? A London Eye Ferris wheel in London has a diameter of 120 m. The wheel rotates...
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 4.7 kg and diameter 0.32 m . The potter then throws a 2.9-kg chunk of clay, approximately shaped as a flat disk of radius 7.0 cm , onto the center of the rotating wheel. Part A What is the frequency of the wheel after the clay sticks to it? Ignore friction.
A wheel (radius = 0.20 m) starts from rest and rotates with a constant angular acceleration of 2.0 rad/s2. At the instant when the angular velocity is equal to 1.2 rad/s, what is the magnitude of the total linear acceleration (in m/s2) of a point on the rim of the wheel? 0.29 0.4 0.49 0.69
An ordinary workshop grindstone has a radius of 9.00 cm and rotates at 8000 rpm. (a) Calculate the magnitude of the centripetal acceleration at its edge in m/s2 and convert it to multiples of g. (b) What is the linear speed of a point on its edge? m/s
A point on the rim of a 0.25 m radius rotating wheel has a centripetal acceleration of 4.0m/s2. What is the angular speed of the wheel? 4.0 rad/s is the correct answer.
number 2 and 3 please 2. A disk of radius 10.0 cm spins about an axis through its center at a constant 5.0 rad/s. What is the linear velocity, centripetal and tangential accelerations of a point on its rim? linear velocity = centripetal acceleration = tangential acceleration = 3. Under what conditions is the linear momentum of a system conserved? (Do not state when the initial is equal to the final.)
