Respuesta :
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 = [tex]\frac{\text {final velocity}+\text {inital velocity}}{2}[/tex]
Although, [tex]\text {averge velocity}=\frac{\text {total displacement}}{\text {total time}}[/tex]
But here, there is only given initial and final velocity therefore it will be simply an average of the two.
[tex]\text {average velocity}=\frac{10+28}{2}=\frac{38}{2}=19 \mathrm{m} / \mathrm{s}[/tex]
Therefore, the average velocity of the object is 19 m/s.
