Find the length of the arc intercepted by a central angle of 3 radians in a circle of radius 13 cm. If ½¾ À make Á Â revolutions about its axis, find the angular displacement Ã of point A. Express your answer in radians. If ½Ä À has an angular displacement of Ã ± Å Â Æ rad, find the number of revolutions ½Ä À makes around its axis. Find the angular velocity ² in both radians per minute and radians per second for a wheel turning at the given number of revolutions. 40 rpm (what does rpm mean?) 65 rpm (what does rpm mean?)
