To solve this problem, let's analyze the given data and apply Newton's second law of motion.

Given Information:

• Mass of the sled (m): 2.0 kg
• Velocity vs. Time Graph: Shows a linear increase in velocity, indicating a constant acceleration.
• Objective: Determine the net horizontal force acting on the sled.

Step-by-Step Solution:

1. Determine the Acceleration from the Graph:

   • Since the velocity vs. time graph is linear, we can calculate the acceleration using the slope of the line.
   • The graph shows an increase in velocity from $0 \, \text{m/s}$ to $10 \, \text{m/s}$ over $8 \, \text{s}$.
   • Acceleration (a) is given by: $a = \frac{\Delta v}{\Delta t} = \frac{10 \, \text{m/s} - 0 \, \text{m/s}}{8 \, \text{s}} = 1.25 \, \text{m/s}^2$

2. Apply Newton’s Second Law:

   • Newton's second law states that the net force $F$ acting on an object is given by $F = m \cdot a$.
   • Substituting the values: $F = 2.0 \, \text{kg} \times 1.25 \, \text{m/s}^2 = 2.5 \, \text{N}$

3. Compare with Options:

   • The calculated net force $F = 2.5 \, \text{N}$ is closest to none of the given options directly, but it suggests that this is a calculation problem. If we confirm with exact slope
