If the average velocity of a body is equal to the mean of its initial

1.	If the average velocity of a body is equal to the mean of its initial velocity and final velocity, then the acceleration of the body is:A. variable B. zero C. negative D. uniform
Answer» If the velocity of the body is always changing with a uniform rate (uniform acceleration), then the average velocity is given by, \(Average Velocity =\frac{Initial\,Velocity\,+\,Final\,Velocity}{2}\) \(\bar{v}=\frac{u+v}{2}\) Hence option D is correct

If the average velocity of a body is equal to the mean of its initial velocity and final velocity, then the acceleration of the body is:A. variable B. zero C. negative D. uniform

Answer»

If the velocity of the body is always changing with a uniform rate (uniform acceleration), then the average velocity is given by,

\(Average Velocity =\frac{Initial\,Velocity\,+\,Final\,Velocity}{2}\)

\(\bar{v}=\frac{u+v}{2}\)

Hence option D is correct
