Two wheels of moment of inertia 4.4 kg.m² and 4.4 kg.m² are set in rotation with angular speed 4.5 rad/s and 9.9 rad/s, respectively. When they are coupled face to face (as shown in the following figure) they rotate with a common angular speed w due to frictional forces, then what is the change in kinetic energy (0) of the wheels due to frictional forces?

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 272-mile trip in a typical midsize car produces about 3.25 x 10° J of energy. How fast would a 18.3-kg flywheel with a radius of 0.303 m have to rotate to store this much energy? Give your answer in rev/min. Number i Units
A solid ball of mass 0.10 kg and radius 2.8 cm is released from rest on a no-slip surface at a height of 0.75 m above the bottom of the track, as shown. After reaching its lowest point, the ball begins to rise again, this time on a frictionless surface. Find: a) the ball's angular speed when it is on the frictionless side of the track and b) the height ball rises on the w = 120 rad/s; h = 0.54 m frictionless side.
1. A circular object of radius R starts from rest and rolls down an incline of M, I height H without slipping. The object has a mass M, a moment of inertia / and a radius R. We go through the steps in finding the speed of the object at the bottom of the incline below, a. What is the total mechanical energy of the object at the top of the incline? Write your answer in terms of I, M, R, H and/or g. b. What is the total mechanical energy at the bottom of the incline in terms of the speed v and the givens? Use the relation v = wR to eliminate the angular speed from your expression. Check that your expression has the correct dimensions. Your final expression should only contain v, I, M, R and/or g. When an object rolls without slipping, the point in contact with the ground is at rest. Therefore, the friction the mechanical energy C. force has displacer work, conserved. Use conservation of mechanical energy to find the speed v of the object at the bottom of the hill in terms of I, R, M,H…
