Two vectors are given by A-bar = 4.0 X-bar â€“ 2.0 y-bar and B-bar = 1.0 x-bar + 5.0 y-bar. What is (a) A-bar + B-bar, (b) B-bar â€“ A-bar, and (c) A vector such that A-bar + B-bar + C-bar = 0? The x-and y-components of an acceleration vector are 3.0 m/s2 and 4.0 m/s2, respectively. (a) The magnitude of the acceleration vector is (1) less than 3.0 m/s2, (2) between and 3.0 m/s2 and 4.0 m/s2 (3) between and 4.0 ...A block weighing 50 N rests on an inclined plane.
