Question

the average velocity of the body 10 m/s and final velocity is 20m/s then intial velocity of the body is ​

Answer 1

Here your answer is :

.

Given ,

av.V = 10m/s

v = 20 m/s

Now ,

av.V = v - u

10 = 20- u

u = 20 - 10

u = 10m/s

So , the required answer is 10m/s.

Answer 2

Answer:

intial velocity is 0 m/s

Explanation:

Given, average velocity= 10 m/s

final velocity= 20 m/s

then , average velocity=( v+u)/2

10m/s=( 20+u)/2

10 ×2= 20+u

20= 20+u

20-20= u

u =0

there fore ,intial velocity is 0 m/s
