Name: Angular Accelerations of a Record Player Category: Rotational Motion Date Added: 2017-07-11 Submitter: Flipping Physics A record player is plugged in, uniformly accelerates to 45 revolutions per minute, and then is unplugged. The record player (a) takes 0.85 seconds to get up to speed, (b) spends 3.37 seconds at 45 rpms, and then (c) takes 2.32 seconds to slow down to a stop. What is the average angular acceleration of the record player during all three parts? Want Lecture Notes? This is an AP Physics 1 topic. Content Times: 0:08 Translating the problem 2:35 Solving part (a) - angular acceleration while speeding up 3:13 Solving part (b) - angular acceleration at a constant angular velocity 3:57 Solving part (c) - angular acceleration while slowing down 4:36 Reflecting on all 3 parts simultaneously Multilingual?
