Question
**Problem Statement:** An athlete exercises his arm by raising the mass \( m \). The shoulder joint \( A \) is stationary. The distance \( AB \) is 300 mm, and the distance \( BC \) is 400 mm. At the instant shown, \( \omega_{AB} = 1 \, \text{rad/s} \) and \( \omega_{BC} = 1.4 \, \text{rad/s} \). --- **Question:** **Part A** How fast is the mass \( m \) rising? (in mm/s) - **Express your answer with the appropriate units.** **Answer Box:** - \( v_m = 969 \, \text{mm/s} \)
