A point at distance R from the center has moved an angle . A wheel of radius R rotates about a fixed axis thru its center. A wheel of radius R rotates about a fixed axis thru its center. A point at distance R from the center moves a distance of 4m. A wheel of radius R rotates about a fixed axis thru its center.
Stars originate as large bodies of slowly rotating gas.
Because of gravity, these clumps of gas slowly decrease in size. A wheel is subjected to constant angular acceleration. Find the angle turned in radians. Problem 27, page 297. Problem 34, page 297.
