To find the net force acting on the sled, you can use Newton's second law of motion, which states that:
\[ F = m \cdot a \]
where:
- \( F \) is the net force,
- \( m \) is the mass of the object,
- \( a \) is the acceleration.
In this case:
- \( m = 15 \, \text{kg} \)
- \( a = 5 \, \text{m/s}^2 \)
Plugging in the values:
\[ F = 15 \, \text{kg} \cdot 5 \, \text{m/s}^2 = 75 \, \text{N} \]
Thus, the net force acting on the sled is **75 N**, which corresponds to option **C. 75 N**.
\[ F = m \cdot a \]
