2. Two industrial spies sliding an initially stationary 255 kg floor safe a displacement d of magnitude 8.50 m. The push F, of spy 001 is 12 N at an angle of 30° downward from the horizontal. The pull F of spy 002 is 10 N at 40° above the horizontal. The magnitudes and directions of these forces do not change as the safe move, and the floor and safe make frictionless contact. Spy 002 Spy 001 Safe 40.0° 30.0° a) What is the net work done on the safe by forces and during the displacement?
