Answer

### The change in velocity $\Delta v$ is $19.6 \, \text{m/s}$.

Explain

## Step1: Identify the given values<br />### The problem provides the average acceleration $\bar{a} = 9.8 \, \text{m/s}^2$ and the time interval $\Delta t = 2 \, \text{s}$.<br />## Step2: Use the formula for change in velocity<br />### The formula for change in velocity $\Delta v$ is given by $\Delta v = \bar{a} \cdot \Delta t$.<br />## Step3: Substitute the given values into the formula<br />### Substituting $\bar{a} = 9.8 \, \text{m/s}^2$ and $\Delta t = 2 \, \text{s}$ into the formula, we get:<br />\[\Delta v = 9.8 \, \text{m/s}^2 \times 2 \, \text{s}\]<br />## Step4: Calculate the result<br />### Performing the multiplication:<br />\[\Delta v = 19.6 \, \text{m/s}\]
