Stopping and redirecting a motorcycle is INSANE, a scientific analysis. #FalconAndWinterSoldier

Stuff that is heavy and moving very quickly has a lot of momentum, a product of m*v. Changing that momentum over time takes a force...F=m*(v/t) or F=ma. Boom! Newton’s second

Let’s say a 600lb bike moving 35mph. In the movie, bike stops in ~1-2s real-time. Plugging this all in to @Wolfram_Alpha (which does the conversions for us), we’re looking at 5,000-20,000N of force, depending on reasonable assumptions.

This is in the region of an arm-ripping-off force, which means Bucky not only needs a metal arm, he needs superhuman *connections* between the limb and the rest of his body.

Oh and one time I asked Seb Stan on stage that I grew my hair out because of him and he said Bucky should have be blonde like me. So there.
