What energy is required to stop three planets the size of earth from colliding on each other

The Causality said:
Bleach have the same feat so I thought about that
I see,but I didn't get your answer tho,if you were to stop three planets with sheer power which are already close to interlocking with eachother with an effect of planetary earth quakes, wouldn't that be above baseline planet level tho??
 
This is pretty weird I don't really know but if these 3 planets are completely destroyed, it's above Baseline if not IDK

Ah,maybe it's your first time seeing this question,sorry if it seems weird tho,to put my points clearly, when three planets comes too close to each other they cause a devastating environmental destruction on their surfaces before they hit due to their gravity pulling on each other at least that's what I read from a site,so I was asking what energy would be required from stopping them at that point with sheer power.
 
Depends on how fast they were moving. If you know that, then you can just throw in the KE formula and multiply by 3

The thing is,this is just a random question,so there is no way I can get a speed,but is there a case for assumption or average speed for the movement of a planet??let say the planet wasn't pushed by anybody,it just roamed freely, note" the three planets are moving at each other not just one planet moving at another.and I need someone to calc it for me,am not good at calcs that much lol,especially if it deals with ap.
 
The energy would be equivalent to greater than the KE of the three planets combined.

KE = 1/2m x v^2

m = mass in kg

v = velocity in m/s

If we assume exact Earth conditions as in RIGHT NOW (not in the gravitational pull of some other planet like object at close range, as that would severely alter results), we have a velocity equivalent to 30000 m/s (roughly) and a mass equivalent to 5.972e24 kg.

KE = (0.5 x 5.972e24) x 30000^2 = 2.688e33 Joules

Multiply by three to get a net value of 8.063e33 Joules, or 1.93 Yottatons of TNT, Planet level+.

Hope this helped.

Yeah thanks a lot,this is what I needed, btw assuming it was only two planets,let's say I want to do it myself, all I should do is to divide your result by two??or would anything else change??
 
nah, just multiply the 2.688e33 by two (5.376e33 btw)
 
I did

5.376e33

It's in the comment you quoted lol

But no worries pal. I am here to help.
