Answer 2

19 m/s is the average velocity if the initial velocity of an object is 10 m/s and the final velocity is 28 m/s.

Explanation:

The initial and final velocity is given and the average velocity is asked, which can be calculated by the following method,

Given that initial velocity = 10 m/s and final velocity = 28 m/s

As we know that the average velocity = $\frac{\text {final velocity}+\text {inital velocity}}{2}$

Although, $\text {averge velocity}=\frac{\text {total displacement}}{\text {total time}}$

But here, there is only given initial and final velocity therefore it will be simply an average of the two.

$\text {average velocity}=\frac{10+28}{2}=\frac{38}{2}=19 \mathrm{m} / \mathrm{s}$

Therefore, the average velocity of the object is 19 m/s.
