Calculation of successful stopping of the car

[Shadow_x007x]

I don't know much about physics, but I'm wondering how we can calculate this feat for Makoto. (Calculate the energy required to stop and the force required to bring the vehicle to a stop.)

I will explain what happened in this scene. First of all, the female character driving the van wants to end her own life by crashing her car into a wall. (That means he didn't press the brakes at all.) Then Makoto pulled the van to a stop.

This feat is also seen in the manga.

You just calculate the kinetic energy of the car. He stopped it in less than a second, so you can scale him to the full energy of the car.

In fact, we already have comparable values in our reference for common feats page.

For force, just find the deceleration of the car and multiple that by the car's mass to get how much force he's exerting. Force = Mass*Acceleration and Deceleration works as well.

Quick example using the above page's values: If the car's was moving at 16.666 m/s, weighs 1332.0576 kg, and he stopped it in 0.5 seconds.

Deceleration = 16.666/0.5 = 33.332 m/s^2

Force = 33.332*1332.0576 = 44400.1439 Newtons or 4.52 Metric Tons (Class 5).

Of course, you'll need to find out exactly how much that car weighs if don't want to use any of the above values. And find out exactly how long it took for him to stop it.

I highly doubt the woman there was following the speed limit either.

We don't need to consider friction, right?
