Fext E An orange ball is subjected to a constant external force Fext (this force is constant in both magnitude and direction). The force Fext has a magnitude of 28.6 newtons and it is directed at an angle theta = 0 = 62.4 degrees north of due east (as shown in red above). While Fext is acting on the orange ball, somebody else grabs the orange ball and moves it a distance 1.22 meters to the east and 1.88 meters to the south. Calculate the work (in joules) that Fext did on the orange ball while it was being moved. (The sign, positive or negative, is important.)
