Three forces acting on an object are given by F1= (-2.00 i + 2.00 j)N. and F2= (5.00i - 3.00j)N. and F3= (-45.0i)N. The object experiences an acceleration of magnitude 3.75 m/s sqr. (a) What is the direction of the acceleration? (b) What is the mass of the object? (c) If the object is components of the object after 10.0s?
