To calculate the motion of a rolling ball, you can use the equations of motion for rotational and translational motion. The translational motion of the ball can be calculated using Newton's second law, taking into account the forces acting on the ball such as gravity and friction. The rotational motion can be calculated using the equations of rotational kinematics, considering the moment of inertia of the ball and any torques acting on it. By combining these equations, you can determine the velocity, acceleration, and position of the rolling ball at any given time. **
