Assume it is a two dimensional problem, the area density of the two circles are the same, and there is no loss to kinetic energy due to friction while it is rolling down.

I'm thinking D only will die because the length of the slope is 5R, which is approximately 80% the "circumference" of the falling circle. Therefore, it will hit D at a solid part of the disk, meaning he would probably get his head crushed.

C only, and you'd need to know the weight of the circles.

Try ducking in two dimensions.

Is E being RKO'd? That'd probably kill a normal person.

E because the rest of them will murder him when they find out he tried to kill them all.

C is not going to die, the boulder or w/e at the top is less massive than the complete one.

WRONG! the shape at the top right is not a circle and is therefore not necessarily the same density

how could he possibley die when the rolling ball is lighter than the ball it's lifting? it won't lift the ball which is heavier.

OP states the densities of the two circles are the same, and there's only one circle in this pic. gg faggot

but if you look closely there is a triangle placed on the right side of the planck. when the lighter circle rolls on it, some of its horizontal velocity will also push down its side of the plank

Wouldn't its kinetic energy just make it jump over that, though?

doesn't the crescent weigh less? It has less mass and has hit a short straight away (and possibly a body) - it has less energy now...so even if it doesn't, the other circle has more mass and C never dies. D can possibly duck down...

I'm going with E. That guy is being grabbed wrongly and that will snap his neck.

You could possibly calculate if it'd tip over if you know what % of the mass is missing, having all the dimensions, the slope's angle and shit, couldn't you?
