Two steel balls, one of mass 1 kg and the other of mass 2kg, simultaneously roll off the edge of the same horizontal table, each leaving with the same
velocity. Which of the following statement is correct?

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.
