Grappler Baki chapter 251, Chiharu Shiba gets hit by a motorcycle during a gang fight.
Quote from the reference page for common feats:
When being hit by an object, the linear momentum of the object+person system needs to remain the same. Linear momentum is m*v
The values vary based on the object and the speed.
For example, assuming the human is 70 kg, the object is 1500 kg and that the object's speed is 11.176 m/s:
FinalSpeed = (ObjectMass*InitialSpeed)/(PersonMass+ObjectMass)
Using the values above this is 10.677707006369426751592356687898 m/s.
KE of the person is 3990.4699419854760842224836707371 Joules
Weight of a motorcycle : ~181kg according to this : https://www.survivaltechshop.com/motorcycle-weight/#:~:text=You%20can%20expect%20an%20average,pounds%20per%20gallon%20of%20gas.
Average weight of an adult male : ~62kg according to this : https://en.wikipedia.org/wiki/Human_body_weight#Ideal_body_weight
Total weight of the motorcycle : ~243kg
Shiba's weight : 72kg
Formula : (MassCar*InitialSpeed)/(MassPerson+MassCar)
