A steel bicycle wheel without the rubber tire is rotating freely with angular speed of 18.00 rad/s. The temperature of the wheel changes from -100.0 to 300.0 º C. No net external torque acts on the wheel and the mass of the spokes is negligible. Does the speed increase or decrease as the wheel heats up? Why? What is the final angular speed

A 3 kg disk of radius 0.25 m is rotating freely at an angular speed of 100 rad/s on a shaft passing through the center if mass of the disk. A 2 kg solid ball of the same radius, initially not rotating, slides down the shaft (the shaft passes through the ball's center of mass) and is coupled to the disk. Assuming that the rotational inertia is of the shaft is negligible, a) what is the angular speed of the...

a bicycle wheel with radius R,mass M,and moment of inertia I=3/4MR^2 is mounted inthe shop so that it can freely turn around a fixed horizontal axis. Someone walking by accidently drops a glob(mass m) of rubber sement on the tire at a point that is a horizontal distance 1/2 R from the wheel's center. the gob has a vertical speed |v| just before it hits. What is the magnitude |w| of the wheel's angular velocity just after the glob hits...

A child pushes her friend (m = 25 kg) located at a radius r = 1.5 m on a merry-go-round (rmgr = 2.0 m, Imgr = 1000 kg*m2) with a constant force F = 90 N applied tangentially to the edge of the merry-go-round (i.e., the force is perpendicular to the radius). The merry-go-round resists spinning with a frictional force of f = 10 N acting at a radius of 1 m and a frictional torque τ = 15 N*m...
