  • If a character, strong enough to lift a building, throws a punch at mach 50, how much force would that yield?

    • Pretty sure it might gonna be 9-A.

    • How do you figure that?

    • Honestly i don't know if it was gonna be correct to give reasons about it to answer or not, i might be wrong about it.

    • I'll calc the punch. KE = 1/2M*V^2

      Average human hand mass = 310 grams = 0.31 KG

      V = mach 50 = 17150 meters per second

      KE = 1/2(0.31)*(17150)^2 = 45,588,987.5 J. which is 9-A, Small Building level

      If I did this wrong, please tell me.

      I'm not doing the building part because buildings can vary. a lot.

      I know this is VERY late, but punches are calculated with the entire mass of an arm, which is approximately 6.5% of the total body weight of a person.

    • So if a 81.6kg man threw a mach 50 punch, it would be 780,325,000 J

      It still would be 9-A, but the Striking Strength would be Small Building Class+, as it is in the upper range, about 0.186 tons of TNT in fact
