Three forces acting on an object are given by F1 = ( 1.95i - 1.60j ) N, F2 = ( - 4.50i - 3.25j ) N, and F3 = ( 46.0j ) N. The object experiences an acceleration of magnitude 3.85 m/s2

(a) What is the direction of the acceleration?
(b) What is the mass of the object?
(c) What are the velocity components of the object after 19.0 s?
