Question 7 of 10 Current Attempt in Progress - Your answer is partially correct. 0.64 m Answers: k= The 1.37-kg uniform slender bar rotates freely about a horizontal axis through O. The system is released from rest when it is in the horizontal position @=0 where the spring is unstretched. If the bar is observed to momentarily stop in the position - 45°, determine the spring constant k. For your computed value of k, what is magnitude of the angular velocity of the bar when 0-30° W = < 0.64 m 106.19 1432 1.37 kg 0.22 mt N/m 0.5/1 rad/s E ***
