SUMMARY
The discussion centers on calculating the position of a particle with constant acceleration that changes direction at t = 4 s and reaches -2 m at t = 10 s with a velocity of -2.4 m/s. The correct position when the particle changes direction is confirmed to be 5.2 m. The user initially calculated the acceleration using the equation v = v0 + at, resulting in a value of -0.24 m/s², and then applied the formula (x2 - x1) = v0(t2 - t1) + 0.5a(t2 - t1)², leading to an incorrect position of 5.68 m. The discrepancy highlights the necessity of considering initial velocity in such calculations.
