is attached to the midpoint of the string. The system is released from rest when the string is fully extended horizontally. Find the velocity of the mass at the instant the ring hits the hook. : Let the hook be the origin . Let the position of mass and the position of mass Set Constraints : The total length of the string is . The segment from the hook to has length . The segment from also has length Analyze the Boundary Condition : When the ring hits the hook, Determine the Geometry : Substituting into the second constraint gives

. Assuming the amplitude of oscillation is small and neglecting higher-order terms of the Earth's angular velocity Ωcap omega , derive the angular velocity ωpomega sub p is attached to the midpoint of the string

These books are considered the bibles of Olympiad physics. Most contain full solutions or sufficient hints. : Let the hook be the origin

To solve this, we must use a non-inertial frame of reference or write the geometric constraint equations. Let's use the ground frame and define coordinates. The segment from also has length Analyze the
