Anna, Alison and Aaron pull on a toy exerting forces as described in the diagram below. Let 5. north be positive and south be negative. Determine the net force acting on the toy. [140 N, north S - + N F1 = 100 N F3 = 110 N F2 = 150 N 6. Three forces act on an object. Two are pulling to the south, one with a magnitude of 35 N and the other with a magnitude of 23 N. The third force is pulling towards the north with a magnitude of 29 N. Determine the net force acting on the object. [29 N, south] 7. Two forces pull on an object. One force pulls with 30 N to the west. The second force is unknown. Determine the unknown force if the net force is 40 N to the east. [70 N, east] A 20 N force pulls to the north on a 10 kg object while a 35 N force pulls to the south. Determine the object's acceleration. [1.5 m/s', south] 9. Fill in the blank to complete the sentence. When two forces act in opposite directions on an object, the object will accelerate in the direction of the force. [Appendix A] pyright Resource Devel
