what is the average velocity if the initial velocity of the object is 10 m/s and the finial velocity is 28 m/s

19m/s

Hope this answer is right!!

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

Average velocity = final velocity+initial velocity/2

Although, average Velocity=total displacement/total time

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

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

f=ma a/f/m a= 480/60 a = 8m/s/s that is quick wow

multiply 2kg by latent heat of vap
