Answer:
The sponge must go [tex]\dfrac{636}{m}\ \text{meter}[/tex] deep
Explanation:
If F = 6360 N, then it is required to find how deep can an object with this force hitting on a sponge get.
We know that, F = mgh
m is mass
g is acceleration due to gravity
[tex]h=\dfrac{F}{mg}\\\\h=\dfrac{6360}{10m}\\\\h=\dfrac{636}{m}\ \text{meter}[/tex]
So, the sponge must go [tex]\dfrac{636}{m}\ \text{meter}[/tex] deep.
