A thin, uniform, rectangular sign hangsvertically above the door of a shop. The signis hinged to a stationary horizontal rod alongits top edge. The mass of the sign is 2.40 kgand its vertical dimension is 50.0 cm. Thesign is swinging without friction, becoming atempting target for children armed withsnowballs. The sign is released from rest froma position that makes a 25,0° angle from thevertical. Assume it swings freely with no airresistance.At a moment when the sign is vertical andmoving to the left, a snowball of mass 400 g,traveling horizontally with a velocity of 160cm/s to the right, strikes perpendicularly thelower edge of the sign and sticks there.a) Calculate the angular speed (WB) of thesign at the lowest part of the swing (justbefore the snowball hits the sign).b) Calculate its angular velocity(magnitude and direction) of the systemimmediately after the impact of thesnowball. Take ccw is positive and cw isnegative. | 25°WA=0We=?
