f = frequency T = period The floor pushes the person toward the center of the circle. Even though the force is inward, it feels the opposite. The ball wants to go in a straight line due to its inertia Rolling without slipping Rolling wheel All three masses are part of a rigid body that have the same rotational velocity Solve for RA and RB RA + RB = F τA = 0 = RB(x1 + x2) – Fx1 All parts of rotating disk have same angular acceleration
