= 18.84 rad/s.

c. Va = 18.84 m/s = Angular velocity.

**shrijana**, Thursday, April 18, 2013 at 4:29pmFreda Pulliam and Yank Hardy are on opposite sides of a canal, pulling a barge with tow ropes. Freda exerts a force of 50 pounds at 20 degrees to the canal, and Yank pulls at an angle of 15 degrees with just enough force so that the resultant force vector is directly along the canal. Find the number of pounds with which Yank must pull and the magnitude of the resultant vector.
