[SOLVED] Another angular acceleration problem. Converting radians to meters... 1. The problem statement, all variables and given/known data A gyroscope flywheel of radius 3.13 cm is accelerated from rest at 15.0 rad/s2 until its angular speed is 2760 rev/min. (a) What is the tangential acceleration of a point on the rim of the flywheel during this spin-up process? m/s2 (b) What is the radial acceleration of this point when the flywheel is spinning at full speed? m/s2 (c) Through what distance does a point on the rim move during the spin-up? m 2. Relevant equations X=Xo + Vot +1/2(a)t(squared) V= Vo +at V(squared) + Vo (squared)= 2a(x) Replace x with radians, V with angular velocity (W), and a with angular accelation 3. The attempt at a solution Working out a and b wasn't difficult, but finding c proved difficult. I first converted the radius to meters. I calculated both parts a and b. In part a I converted 2760rev/min to 289.03rad/s and converted the radius given in cm to m. Then I multiplied both and got a small tangential acceleration of .4695. Next for part b I calculated the radial acceleration by using the 289.03rad/s(squared) and multiplying it by the radius. For part c I found the hypotenuse acceleration of both of these by pythagorean's theorem and then I tried to use the basic kinematics equations converted to angular values for my answer and ended up getting 2784.54 radians. So after that I tried to divide it by 2times pie to convert it over to meters getting 443.17meters, but for some reason I still got it wrong. Did I convert it wrong?
