# An object moves along the \(x\)-axis subject to a net force. The graph shows the object’s linear momentum \(p\) as a function of time \(t\), where the segment from \(t = 2.0\text{ s}\) to \(t = 5.0\text{ s}\) is linear and changes from \(p = 8.0\text{ kg}\cdot\text{m/s}\) to \(p = -4.0\text{ kg}\cdot\text{m/s}\). What is the net force exerted on the object at time \(t = 3.0\text{ s}\)?

An object moves along the \(x\)-axis subject to a net force. The graph shows the object's linear momentum \(p\) as a function of time \(t\), where the segment from \(t = 2.0\text{ s}\) to \(t = 5.0\text{ s}\) is linear and changes from \(p = 8.0\text{ kg}\cdot\text{m/s}\) to \(p = -4.0\text{ kg}\cdot\text{m/s}\). What is the net force exerted on the object at time \(t = 3.0\text{ s}\)?

![A Cartesian coordinate graph with time t in seconds on the horizontal axis and linear momentum p in kg*m/s on the vertical axis. The horizontal axis has tick marks and integer labels at 0, 1, 2, 3, 4, 5, 6, and 7. The vertical axis has tick marks and even integer labels from -6 to 10 in steps of 2. Light gray gridlines align with each integer tick mark on both axes. A single continuous thick solid line starts at (0, 0), extends straight to (2, 8), continues straight down to (5, -4), and then extends horizontally to (7, -4). No other labels, lines, text, or axes appear.](https://nerd-notes.com/wp-content/uploads/ubq-frq-generated/stem-fig-1-1787460184-01ShUg.jpg)
