A body A begins to move with initial velocity 2 m/sec and continue to moves at a constant acceleration \[a.\text{ }\Delta \text{t}=10\] seconds after the body A begins to move a body B departs from the same point with an initial velocity 12 m/sec and moves with the same acceleration a. What is the maximum acceleration a at which the body B can overtake A?

• A. \[1\text{ }m/{{s}^{2}}\]
• B. \[2\,m/{{s}^{2}}\]
• C. \[1/2\text{ }m/{{s}^{2}}\]
• D. \[3\text{ }m/{{s}^{2}}\]
