Answer

### C) \(480 \, \text{J}\)

Explain

## Step1: Identify the work formula<br />### Work (\(W\)) done by a force (\(F\)) is \(W = F \cdot d\), where \(d\) is the distance.<br />## Step2: Find the distance covered<br />### Distance (\(d\)) is given by the velocity (\(v\)) multiplied by time (\(t\)): \(d = v \cdot t = 2 \, \text{m/s} \cdot 6 \, \text{s} = 12 \, \text{m}\).<br />## Step3: Calculate the work done<br />### Using the formula \(W = F \cdot d\): \(W = 40 \, \text{N} \cdot 12 \, \text{m} = 480 \, \text{J}\).
