1. The problem statement, all variables and given/known data A turntable rotates counterclockwise at 78rpm, a speck of dust on the turntable is at 0.42rad at t=0 ,What is the angle of the speck at t = 8.0s ? Your answer should be between 0 and 2π rad Express your answer using two significant figures. 2. Relevant equations θf-θi=ωt 3. The attempt at a solution I missed a couple of classes so I'm incredibly behind. I've been trying to google how to do things but it's not really working out for me, so if something is wrong let me know (which it obviously is or I wouldn't be here). So, I started out by converting the 78 rpm measurement into an angular velocity 78rpm x 2∏ x 1/60 = 8.168rad/s Then by using the formula for Δθ (θf-θi=ωt) θf=ωt+θi 8.168(8)+0.24rad = 65.585 rad. I've tried 66 rad and 65 rad just to see if that helped at all, but to no avail. I know it says that my answer is supposed to be between 0 and 2pi and that 65.5 is far larger than 2pi, what else am I supposed to do? I've done my best at the problem... I don't know what else to do.
