User blog:Edwardtruong2006/FSI:A: Fish Spiders punting over trees

Alright so Fish Spiders knock down trees. We're allowed to get this via the KE of the tree.

So basically, they're able to knock down trees which according to this are 38 m^3.

This is a White Oak so 770 kg/m3

770*38 = 29260 kg.

Now for the speed we need the height. 30 meters according to the blog above.

30*pi = 94.2477796077 meters the tree had to travel.

It takes around 3 seconds for it to fall so, 94.2477796077/3 = 47.1238898038.

Now for KE

0.5*31.4159265359^2*29260 = 14 megajoules Wall level+ alright.
