QUESTION 5 A figure skater is spinning with an angular velocity of Il rad/s. She then comes to a stop over a brief period of time. During this time, her angular displacement is 5.9 rad. Determine her average angular acceleration, in SI units, with 3 or more significant figures QUESTION 6 Suppose you exert a force of 171 N tangential to a 0.26 m radius 83 kg grindstone (a solid disk). What is the angular acceleration if there is an...
