1. The problem statement, all variables and given/known data Two forces act on an object of mass 2.5kg; force F1 that is directed alont the +x-direction and has magnitude of .50N and force F2 that points at a 45 degree angle in the +y and -x quadrant and has magnitude 2.0N. Find the additional force, if any such that the object will accelerate in the +y direction with magnitude 1.5m/s/s. 2. Relevant equations F=ma Fnet=F1+F2+F3+etc... F=Fsin[tex]\theta[/tex] 3. The attempt at a solution Fnety= F2sin[tex]\theta[/tex]+FX-Fg FX= missing force= ? Fnety= (2.5kg)(1.5m/s/s)= 3.75N F2sin[tex]\theta[/tex]= 1.414N Fg= 2.5*9.8=24.5N 3.75 = FX + 1.414 -24.5 FX= 26.84N I'm not sure if I'm even trying to go about the problem correctly. The selected answers in the back of the book has the answer as: (0.91N)i+(2.3N)j so I'm really confused.
