Answer:

Let u be the initial velocity

∴v

1

=u+at

1

,v

2

=u+a(t

1

+t

2

)

and v

3

=u+a(t

1

+t

2

+t

3

)

Now v

1

=

2

u+v

1

=

2

u+(u+at

1

)

=u+

2

1

at

1

v

2

=

2

v

1

+v

2

=u+at

1

+

2

1

at

2

v

3

=

2

v

2

+v

3

=u+at

1

+at

2

+

2

1

at

3

So (v

1

−v

2

)=−

2

1

a(t

1

+t

2

)

and (v

2

−v

3

)=−

2

1

a(t

2

+t

3

)

∴(v

1

−v

2

):(v

2

−v

3

)=(t

1

+t

2

):(t

2

+t

3

)
