Chapter 5, Problem 30PQ

Three forces ${\stackrel{\to }{F}}_{\text{1}}=(62.98\hat{i}-15.80\hat{j})$ N, ${\stackrel{\to }{F}}_{\text{2}}=(23.66\hat{i}-78.05\hat{j})$ N, and ${\stackrel{\to }{F}}_{\text{3}}=(-86.64\hat{i}+233.4\hat{j})$ N are exerted on a particle. The particle’s mass is 14.23 kg. Find the particle’s acceleration.
