The 2oz bullet (=2/16 lbf) has a horizontal velocity of 1500ft/s as it strikes the 20lb slender bar OA, which is suspended from point O and is initially at rest. Calculate the angular velocity w which the bar with its embedded bullet has acquired immediately after impact. If the bullet takes 0.001s to embed itself in the bar, calculate the time average of the horizontal force Ox exerted by the pin on the bar at O during the interaction between the bullet and the bar. x 15" * 15" A 1500 ft/sec
