A potter's wheel having a radius 0.45 m and a moment of inertia of 13.2 kg. m² is rotating freely at 48 rev/min. The potter can stop the wheel in 8.0 s by pressing a wet rag against the rim and exerting a radially inward force of 69 N. Find the effective coefficient of kinetic friction between the wheel and the wet rag. 0.261 X

a 4kg block is attached to the vertical pole by two strings. when the system rotates about the axis of the pole the two strings are extended as shown in the diagram, the tension in the upper string is 88N. find the tension in the lower string, the rev/min the system makes normally and when the lower cord just goes slack.

Two blocks of the same masses (m 1.5 kg) are attached to end of a rope that passes over a pulley %3D suspended from the ceiling. The pulley is a uniform disk (Idisk=MR?), with mass M = 3 kg and radius R = 20 cm. When the block is released and the cord unwinds, the acceleration of the blocks ( in m/s) is: m

A potter's wheel having a radius 0.52 m and a moment of inertia of 11.3 kg · m2 is rotating freely at 53 rev/min. The potter can stop the wheel in 6.0 s by pressing a wet rag against the rim and exerting a radially inward force of 68 N. Find the effective coefficient of kinetic friction between the wheel and the wet rag.

The two blocks are connected by a massless rope that passes through a pulley. Mass of first block is m1 = 1 kg, mass of the second block is m2= 5 kg. Mass of the pulley is M = 2 kg. Radius of the pulley is R= 10 cm. First block is placed on the 30 incline and the second block is hanging above the table at the height of 40 cm. Then, the system is released and the first block starts sliding up the incline and the second block starts falling toward the table. a) forces that apply to the pulley. b) pulley. Consider the pulley to be a disc and use disc's moment of inertia(/ = MR?/2) c) acceleration of the blocks. Draw the FBD for both blocks and draw separately the Write down equations of motion for the blocks and Using the equations from part (b) to calculate the Finally, find the velocity that the second block will d) acquire just before hitting the table using energy. m1 m2

Problem 1: Consider a small block weighing 200 grams that is placed 10 cm from the center of turntable. The turntable slowly begins to spin. If the static friction coefficient is g = 0.4, at what angular velocity will the block begin sliding off the turntable?

One end of a string is wrapped several times around a pulley of mass  0.92 kgkg  that is oriented vertically. The other end of the string is connected to a block of mass 0.35 kg, which is then slowly lowered until the string becomes taut. After which the person lets go of the block completely, thus allowing the block to descend and the pulley to rotate in unison. What is the magnitude of the acceleration of the block after the person has let go?

Pls answer all of it and box the answers thank you
