A figure skater performs a twisting jump. She rotates around her longitudinal axis 2 times in 0.65 s.  What was her average angular velocity in radians/second? A   720rad/s  B   19.3rad/s C   4? rad/s D   9.67 rad/s E   1107 rad/s

the angular velcoity of an airplane propeller increases from 12 rad/s to 16 rad/s while turning through 7 rad. What is the angular acceleration in rad/s^2?

A merry-go-round is a common piece of playground equipment. A 5 m diameter (that's diameter) merry-go-round rotates frictionlessly. It has a mass of 166 kg and is spinning at 22 rpm (that's revolutions/minute... you will want to convert to radians/sec). John runs tangent to the merry-go-round at 2.5 m/s in the same direction that it is turning. John's mass is 27 kg. He then jumps onto the MGR and sits halfway between the outer edge and the center.   (A)What is the initial angular momentum, LJ, of John? (B)What is the total initial angular momentum of the system? (C)Use Conservation of Angular Momentum to find the final angular speed of the merry-go-round?

A ball rolling down a ramp accelerates steadily from 1.5 rad/s to 5.5 rad/s at an angular acceleration of .50 rad/s^2. What total angular distance does it travel in this time? ____ rad (two significant figures- round to the ones place)
