Option 1 -

Impulse and average force acting on the object will be same for both the cases.

Option 2 -

Impulse and average force acting on the object will be same for both the cases.

Option 3 -

Average force will be same for both the cases but the impulse will be different.

Option 4 -

Average force and impulse will be different for both the cases.

$v_{1} = \sqrt[]{2 g 10}$

$v_{2} = \sqrt[]{2 g 5}$

$\vec{l} = Δ \vec{p}$

$l = 0.1 {\sqrt[]{2 g 10} + \sqrt[]{2 g 5}}$
