Hello, this is related to My Hero Academia. Some time ago you suggested me to use 5 psi instead of 20 psi for the landmine explosions of the Sports Festival, since we don't know if they could break concrete.
However, I recently calculated the speed at which these explosions send the students and got Subsonic results (37.5 m/s), resulting in a kinetic energy of 43945.3 joules (using the average japanese male weight).
And my question is this, isn't that enough to break concrete? And justify 20 psi? I don't even know if a 20 psi explosion could send people flying that fast.
