Meriam, Kraige & Bolton — Plane Kinetics of Rigid Bodies: Problem 6_140

6/140 The man is walking with speed \( v_1 = 1.2 \text{ m/s} \) to the right when he trips over a small floor discontinuity. Estimate his angular velocity \( \omega \) just after the impact. His mass is \( 76 \text{ kg} \) with center-of-mass height \( h = 0.87 \text{ m} \), and his mass moment of inertia about the ankle joint \( O \) is \( 66 \text{ kg} \cdot \text{m}^2 \), where all are properties of the portion of his body above \( O \); i.e., both the mass and moment of inertia do not include the foot.
