The image you uploaded is a bit blurry, but I will try to interpret it as accurately as possible.

From what I can see, the problem involves finding the percent error for a value of acceleration, with a measured value of 7.5 m/s² and a true value of 7.8 m/s².

To calculate the percent error, we can use the formula:

$\text{Percent Error} = \left( \frac{|\text{Measured Value} - \text{True Value}|}{\text{True Value}} \right) \times 100$

Let's plug in the values:

• Measured Value = 7.5 m/s²
• True Value = 7.8 m/s²

The formula becomes:

$\text{Percent Error} = \left( \frac{|7.5 - 7.8|}{7.8} \right) \times 100$

Now let's calculate this.

$\text{Percent Error} = \left( \frac{0.3}{7.8} \right) \times 100 \approx 3.85\%$

So, the percent error is approximately 3.85%.
