# Question #6aed0

This is a bit like Zeno's Dichotomy paradox. You will find that by reducing velocity as you indicate you get this pattern:

$v \to v \cdot 0.9 \to v \cdot {0.9}^{2} \to \ldots . \to v \cdot {0.9}^{n} \to \ldots .$

So you never get to zero.

You will improve your model by specifying that the sheet will reduce the velocity by 90% or some fixed amount that requires the bullet to stop.

$\infty$

#### Explanation:

if we look into the question the velocity decreases to $\frac{1}{10}$ every time it passes through the pane .if we consider that its velocity would be 100$m {s}^{- 1}$ after first pane it will decrease to 10 m/s and so on but never be zero .
