Padme

[Logic]

Yall remember that scene on geonosis where we jumped onto that Reek? Well Lets talk about that. 

-The poles were 3 Obi Wans in height
-Ewan McGregor is 1.77 meters tall.
-If you subtract the height of the reek from the height of the pole you get the total distance she fell
-Natalie Portman (Padme) is 53.5kg, and the gravity on Geonosis is 90% standard. (Standard is defined as 9.81 Meters per second^2)
-Using that, acceleration on Geonosis is 8.82 meters per second^2
-Using the work energy principle padme collided her coochie onto that reek with 14,432 Newtons of force
-A femur takes 4000 newtons to break.

Padme got balls of steel

I stopped at "collided her coochie"

[Harsh]

I wanted to write this out because I thought it would be fun. Is this what you guys did?

Using the distance/velocity kinematic equation: 

vf^2= vo^2 + 2a∂x

vo=0 m/s (assuming padme had no vertical velocity upon jumping)

∂x = 3 x 1.77 - 1m (1m is the assumed height of the creature)

Thus: vf^2 = 0 + 2 x 8.82 x 4.31 

This can be approximated to: vf^2 = 64 or vf = 8 m/s.

According to the Work-Energy Theorem: 

Work = Kf - Ki 

We want to know the force exerted on Padme as she impacts the creature, so we will say that her final velocity is 0 (when she hits the creature, her velocity becomes 0) and her initial velocity is the vf we found above, 8 m/s. 

Thus: 

Work = 0 - (.5) (54 kg) (8 m/s)^2

Work = -1728 Joules

Work = Force x Distance

Let's assume that the force decelerating Padme was applied over 10 cm

-1728 Joules = Force x 0.1m

Force = -17,280 Newtons

That's a lot of force. Why tf was she not evaporated instantly?

(Edit): Alternatively, we could estimate the energy required to break a bone to be around 400 Joules (from a quick google search), so that's around 3x the energy required damn

Bold of you to assume I paid more attention than what was written on the slide

But that looks right

[Bleach]

Ah yes. Simple.

I saw a video on this the other day. Nice copy pasta though!
