## Homework Statement

A boy throws a ball with v velocity upwards as well as downwards . What will be the displacement covered by the two balls if air friction and external force or viscosity is neglected ?

## Homework Equations

According to me the equations of motions are relevant here .

## The Attempt at a Solution

ummm

I case :

u=0

t= 1 sec to gain velocity v

v= v

then s(displacement) = 1/2t(v+u)

= 1/2v

II case :

u2=0

t2= 1 sec to gain velocity v

v= v

then s2(displacement) = 1/2t(v-u)

= 1/2v

If time = t seconds then of course t=t2

So s=s2=1/2v
