A particle is moving at constant velocity. Its position at t = 1.0 s is 3.0 m and its position at t = 4.0 s is 15.0 m. What is the slope of the position-time graph for this particle? A) 0, since this is a constant velocity situation. B) 4.0 m/s C) 4.0 m/s² D) 9.0 m/s E) 12 m/s²

The slope of the position-time graph represents the velocity of the particle. To find the slope (velocity) = (change in position) / (change in time) = (15.0 m - 3.0 m) / (4.0 s - 1.0 s) = 12 m / 3 s = 4.0 m/s.
