1. The problem statement, all variables and given/known data An object of Mass 3 in the x-y plane is subjected to a constant force F (in addition to its weight). The object starts from rest at x=0 y=0 and t=0. At t=2 the object's displacement is 2i+4j. Determine F. 2. Relevant equations 3. The attempt at a solution Where do I begin? I know you have the position it moved so would I use work. Or do I need to find the acceleration and try and Find F that way???
