Cognitive Research Trust (CoRT) by Edward de Bono helps us to focus attention directly on different aspects of thinking and to crystallize these aspects into definite concepts and tools that can be used deliberately. One of the CoRT tools suggested is PMI (Plus, Minus, Interesting). Using this tool, examine the following statement:

The particle p starts from rest at point a at time t = 0 and changes its speed thereafter at a constant rate of 2.8g as it follows the horizontal path shown. determine the magnitude and direction of its total acceleration (a) just before point b, (b) just after point b, and (c) as it passes point c. state your directions relative to the x-axis shown (ccw positive) and choose the angle with the smallest magnitude.
