The 1.2‐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 θ = 0, where the spring is unstretched. if the bar is observed to momentarily stop in the position θ = 50°, determine the spring constant k. for your computed value of k, what is the angular velocity of the bar when θ = 25°?
