1. The problem statement, all variables and given/known data 4. An electric turntable 0.750 m in diameter is rotating about a fixed axis with an initial angular velocity of 0.250 rev/s and a constant angular acceleration of 0.900 rev/s². a) Compute the angular velocity of the turntable after 0.200s my answer:1.35rev/s b) Through how many revolutions has the turntable spun in this time interval? my answer:0.01 c) What is the tangential speed of a point on the rim of the turntable at t = 0.200 s? my answer: 0.51 d) What is the magnitude of the resultant acceleration of a point on the rim at t = 0.200 s? my answer: 6.9 rev/s^s really unsure of this one. 2. Relevant equations 3. The attempt at a solution for d: I found the angular acceleration (alpha) to be 5.5 then using the relationship alpha =a/r to find the translational acceleration. From there i used Pythagoras' theorem to solve for the resultant. I know ive been asking for a lot of checking of my work lately, just because i am not great with the topics were doing this term. I do always have a good attempt at the problem before asking for help. thanks in advance.
