1. A stone artifact is stuck in the mud. Two workers apply equal forces of magnitude 80 N to pull the stone ou mud. The magnitude of the friction force is 120 N. The mass of the stone is 87.0 kg. a) Draw a FBD for the stone. Include all force vectors (F1, F2. Fix, Fly. Fax, Fzy, Fy) in your FBD. backward + + forward b) Find the net force on the stone in the y direction. c) Find the net force on the box in the x direction. d) Find the magnitude and direction of the acceleration
