Question: Answer choice : D. 10.5 rad/s Time left 0:40:00 A propeller consists of five identical planks with mass m =O.4 kg and LamJen . 2
Answer choice : D. 10.5 rad/s

Time left 0:40:00 A propeller consists of five identical planks with mass m =O.4 kg and LamJen . 2 cm, coupled to one of their ends as shown in the figure. At some point the angular velocity of the propeller is winma. = 10.5 rad/s and one of the planks becomes loose. What is angular velocity of the propeller after losing one plank? Select one: Q a. to = 8.5 rad/s O b. u) = 13.1 rad/s O C. to = 6.5 rad/s
