A 34.0 kg wheel, essentially a thin hoop with radius 1.60 m, is rotating at 111 rev/min. It must be brought to a stop in 28.0 s. (a) How much work must be done to stop it? (b) What is the required average power? Give absolute values for both parts.
Question 8. A flywheel is a solid disk that rotates about an axis that is perpendicular to the disk at its center. Rotating flywheels provide a means for storing energy in the form of rotational kinetic energy and are being considered as a possible alternative to batteries in electric cars. The gasoline burned in a 414-mile trip in a typical midsize car produces about 1.32 × 109 J of energy. How fast would a 44.1-kg flywheel with a radius of 0.304 m have to rotate to store this much energy? Give your answer in rev/min. Ans: 343712.61 rev/min

A potter's wheel is a uniform solid disk of radius R = 0.300 m and M = 120 kg. It is initially rotating at 12.0 rad/s. The potter can stop the wheel in 6.00 s by pressing a wet rag against the rim exerting a normal force (radially inward) of 68.0 N. The effect of pressing with the rag produces a frictional torque that brings the wheel to a stop. What is the frictional torque that acts on the wheel while it is %3D slowing down? 125 N-m O - 25.5 N m O - 50.0 N m 12.5 N m O - 10.8 N:m DII 吕口 esc F5 F6 F7 FB F2 F3 F4 @ # $ & Q E R Y D F G K X V 00
