What is the rotational inertia of a solid iron disk of mass 32.0 kg, with a thickness of 5.00 cm and radius of 11.0 cm, about an axis through its center and perpendicular to it?  ____kg⋅m2

In the figure, wheel A of radius -9.40 cm is coupled by belt B to wheel C of radius rc-26.1 cm. The angular speed of wheel A is increased from rest at a constant rate of 2.53 rad/s². Find the time needed for wheel C to reach an angular speed of 63.0 rev/min, assuming the belt does not slip. (Hint: If the belt does not slip, the linear speeds at the two rims must be equal.) Number Ma Units B

Starting from rest, a 10.8cm diameter compact disk takes 7.96s to reach its operating rotational speed of 1920.0 rpm (revolutions per minute). Assume that the angular acceleration is constant. The disk's moment of inertia is 3.88E-5kg.m². How much torque is applied to the disk? Submit Answer Tries 0/10 How many revolutions does it make before reaching full speed? (Do not enter a unit.)
