Question

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

Answer 1

Answer:

• Average velocity = 10 m/s
• Final velocity (v) = 20 m/s
• initial velocity (u) = ?

By applying the formula of average velocity we have :

$\implies Average \: velocity = \dfrac{u + v}{2}$

Substituting the given quantities in the above formula we get :

$\implies 10 = \dfrac{u + 20}{2}$

$\implies u + 20 = 2 \times 10$

$\implies u + 20 = 20$

$\implies u = 20 - 20$

$\implies \underline{ \boxed{ \bf u = 0 \: {ms}^{ - 1} }}$

Hence,the initial velocity (u) of the body is 0 m/s.

Answer 2

Answer:

0

Explanation:

Average Velocity = Vi + Vf/2

Initial Velocity = Vf - (10*2)

Initial Velocity = 20 - (10*2)

Initial Velocity = 0
