A position-vs-time graph with time on the x-axis ranging from 0 to 6 seconds and position on the y-axis ranging from 0 to 20 meters. The graph shows a smooth curve starting at the origin (0,0) and curving upward. At time t = 4 s, the position is x = 8 m. A dashed tangent line is drawn through the point (4, 8). This dashed line clearly passes through the points (2, 0) and (6, 16) on the grid.
Position as a function of time for a car moving along a straight track.
The graph shows the position \(x\) of a toy car moving along a straight track as a function of time \(t\). A dashed line is drawn tangent to the curve at the point where \(t = 4 \text{ s}\). What is the instantaneous velocity of the car at \(t = 4 \text{ s}\)?
