The particle P starts from rest at point A at time t = 0 and changes its speed thereafter at a constant rate of 2.1g as it follows the horizontal path shown. Determine the magnitude and direction of its total acceleration at times t = 0.82 s and t = 1.26 s. State your directions relative to the x-axis shown (CCW positive) and choose the angle with the smallest magnitude. Note: 12.55769377 and 0.7321 have been attempted and they were both incorrect. Thank you and have a nice day ahead.

Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.
