The two slender bars, each having a mass of 4 kg, are hinged at and pivoted at If a horizontal impulse is applied to the end of the lower bar during an interval of 0.1 s during which the bars are still essentially in their vertical rest positions, compute the angular velocity ω₂ of the upper bar immediately after the impulse.
