SUMMARY
The discussion centers on calculating velocity and position from an acceleration-time graph for a particle with an initial position of 10 m and an initial velocity of 9 m/s. The correct formulas to use are v = v_o + at and x = v_ot + (1/2)at^2. The user initially calculated the velocity at 7 seconds as -12 m/s and the position as -0.5 m, which were incorrect. Proper application of the equations is necessary to derive the correct values for both velocity and position.
