Answer 1

Based on the calculations, the average velocity is equal to 360 m/s and the percent difference is equal to 4.72%.

What is average velocity?

An average velocity can be defined as the total distance covered by a physical object divided by the total time taken.

What is an average?

An average is also referred to as mean and it can be defined as a ratio of the sum of the total number in a data set to the frequency of the data set.

How to calculate the average velocity?

Mathematically, the average velocity for this data set would be calculated by using this formula:

Average = [F(v)]/n

Vavg = [v₁ + v₂ + v₃ + v₄ + v₅)/5

Since the values of the average velocity from the table are missing, we would assume the following values for the purpose of an explanation:

• v₁ = 100 m/s

• v₂ = 150 m/s

• v₃ = 200 m/s

• v₄ = 250 m/s

• v₅ = 300 m/s

Substituting the parameters into the formula, we have:

Vavg = [300 + 450 + 500 + 250 + 300)/5

Vavg = 1800/5

Vavg = 360 m/s.

Next, we would calculate the percent difference by using this formula:

$Percent \;difference = \frac{[V_{avg}\;-\;V_{sound}]}{V_{sound}} \times 100$

Percent difference = [360 - 343]/360 × 100

Percent difference = 17/360 × 100

Percent difference = 0.0472 × 100

Percent difference = 4.72%.
