Answer:
3.0 m/s
Explanation:
The instantaneous velocity is the speed of the particle at a given moment. On a position vs. time graph, the instantaneous velocity is the slope of the tangent line that touches the curve at that point.
Drawing the tangent line through the point (1, 0), the slope of the line is approximately:
v = (4.0 m − 0 m) / (2.3 s − 1.0 s)
v = 3.0 m/s
