E C. NAM s: LE ‘1 Section Table 3. [34 pts} The slender bar 13 is 1.2 ft long and weighs 10 lb. At
the inslantjusl prior to contact with the ball, the bar is rotating
about the trietiouless pin 0 with the given angular velocity.
Just prior to contact at point C. the 241:: ball A is traveitng as
shown. The coefficient ot'rcstitution between the hall and bar
is {}_{. The contact surface is I'rietinltioss. The motion is in u
1vertical plane. Find the velocity ol'the hall anti the angular
velocity at the her immediater after the impact event is over. To simplify your arithmetic. please use the coordinate system
