Question

Three forces acting on an object are given by 

F1 = (−1.9î + 5.80ĵ) N,

 

F2 = (4.95î − 2.15ĵ) N,

 and 

F3 = (−44î) N.

 The object experiences an acceleration of magnitude 3.60 m/s2.

Three forces acting on an object are given by F, = (-1.9î + 5.80j) N, F, = (4.95î - 2.15j) N, and F, = (-441) N. The object experiences an acceleration of magnitude 3.60 m/s?.
