Three forces acting on an object are given by F1 = (−1.5î + 7.45ĵ) N, F2 = (5.25î − 1.1ĵ) N, and F3 = (−42î) N. The object experiences an acceleration of magnitude 3.70 m/s2. (a) What is the direction of the acceleration? ° (counterclockwise from the x-axis). (b) What is the mass of the object? kg. (c) If the object is initially at rest, what is its speed after 18.0 s? m/s. (d) What are the velocity components of the object after 18.0 s
