I know this is not typical and you aren't suppose to solve the problem for the person just give hints, however my teacher has not taught this and expects us to know it. For whatever I cannot grasp how to do this any help would be great thank you! 1. The problem statement, all variables and given/known data The turntable of a record player has an angular speed of 3.5 rad/s at the instant it is turned off. The turntable stops 1.6s after being turned off. The radius of the turntable is 15cm. (a) If the angular acceleration is constant, through how many radians does the turntable turn after being turned off? (b) What is the magnitude of the linear acceleration of a point on the rim of the turntable 1.0s after it is turned off? (Hint: The linear acceleration has both a radial and a tangential component). 2. Relevant equations We have not been given any equations yet, we were just told to use the position function and ones used in projectile motion problems. 3. The attempt at a solution for a I got 4.375 I took 3.5(1.6/2). Is this right? I don't really have any reasonings for why I did it. I don't understand how to do b. If you could send me down the right path with that one it would be greatly appreciated.
