A thin homogeneous bar A of length ℓ = 1.75 m and mass m = 23 kg is translating as shown with a speed υ0 = 12 m/s when it collides with the fixed obstacle B. Modeling the contact between the bar and obstacle as frictionless, letting β = 32°, and letting the distance d = 0.46 m, determine the angular velocity of the bar immediately after the collision, knowing that the COR for the impact is e = 0.74.
