SUMMARY
The particle is thrown horizontally with an initial speed of 10 m/s. After 0.2 seconds, the vertical velocity (vy) is calculated using the equation vy = gt, resulting in a value of 2 m/s when using g = 10 m/s². The total speed (v) after 0.2 seconds is determined using the formula v = sqrt(vx² + vy²), yielding a final speed of approximately 10.198 m/s. The discussion highlights the importance of using the correct gravitational constant, with 9.8 m/s² being the standard value for more precise calculations.
