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.

How is science controlled by the governerment

Aforce f making an angle with the horizontal is acting on an object resting on the table. which statement is true for the motion of sliding the object on the table?
