In the illustration below Little Jimmy is pulling on the rope with 120 lbs of force. Perform the following: a. Determine the directional unit vector from Point A to Point B. b. State the force of the rope on Point A in Cartesian vector form. c. Determine the coordinate direction angles of the force with respect to the three axes. d. If Little Jimmy's friend came along with a second rope connected to Point A and pulled straight downward with a force of 150 lbs, what would the resultant force on Point A be? 30 ft -8 ft- 6 ft B 12 ft
