Take the magnitude of the acceleration of gravity near the earth's surface to be 9.80 m/s 2 All three problems deal with forces and the application of Newton's Second Law. Always remember: FORCES ARE VECTORS Definition: the net force F net acting on an object is the (vector) sum of all of the external forces acting on the object.
