    Ball on a Turntable Simple Harmonic Motion

    Here's my work in text format: In part A of my work I determined that angular momentum is conserved about the moving point P. (Point P being the point on the ball in contact with the turntable.) If I'm not mistaken that would mean that the angular momentum at moving point P is coupled to that...

    Ball on a Turntable Simple Harmonic Motion

    Homework Statement A spherical ball of mass “m”, moment of inertia “I” about any axis through its center, and radius “a”, rolls without slipping and without dissipation on a horizontal turntable (of radius “r”) describe the balls motion in terms of (x,y) for a function of time. **The...

    Ball Rolling Without Slipping On A Turntable

    I learned from the links that I have listed in my original post, and tried to follow what they did to the best of my ability. I still kind of confused with the process though. I can understand these steps. 1. Determining angular momentum at center of mass 2. Determining angular momentum at...

    Ball Rolling Without Slipping On A Turntable

    I'm sorry, can you please explain step by step how you got your final answer (including the conversion). I'm still having trouble trying to understand all this. :frown:

    Ball Rolling Without Slipping On A Turntable

    I still don't understand how my professor got ##\frac 7 5##. Do you think he could have made a mistake or is there maybe some alternative way of solving this problem?

    Ball Rolling Without Slipping On A Turntable

    I'm not sure how to write this in terms of r and θ, but I think rotation about the tangential and radial axis will consistent with that of the spinning turntable? The angular momentum at the center of mass will be equal to: (moment of inertia of the ball)*(the balls angular velocity) Lcm = IW...

    Ball Rolling Without Slipping On A Turntable

    I apologize for the delayed response This tells me that the rotation about the tangential and radial axis will consistent with that of the spinning turntable? The angular momentum at the center of mass will be equal to: (moment of inertia of the ball)*(the balls angular velocity) The angular...

    Ball Rolling Without Slipping On A Turntable

    Very interesting, now I just need to find a way to describe the balls motion in terms of (x,y). Do you have any idea how to do that?

    Ball Rolling Without Slipping On A Turntable

    Z (k) points out perpendicular to the turntable, X (i) points out to the right, Y (j) points out 90 degree from x (coordinate system is fixed in space). The spherically symmetric ball of mass “m”, moment of inertia “I” about any axis through its center, and radius “a”, rolls without slipping and...

    Ball Rolling Without Slipping On A Turntable

    Can someone please help me out with this tough problem? 1. Homework Statement A ball rolls on a turntable without slipping describe the balls motion in terms of (x,y) for a function of time. (The turntable spins at a constant rate) (This all the information that the professor gave us.)The...
