Three forces acting on an object are given by F1 = (−2.25i + 6.95j) N, F2 = (5.10i − 1.8j) N, and F3 = (−49.5i) N. The object experiences an acceleration of magnitude 3.90 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? (Let the velocity be denoted by v. ) v = i + j m/s
