Does she have any in-laws?

]]>If so then the thrust needed for Mach 4 at sea level would get her to the moon in 8 seconds with no drag, that includes braking time.

]]>I’d argue it’s more likely to be quadratic – so she was at mach 4, which squared is 16 – so her next upgrade would take her to mach 256. Two more upgrades from that would put her at… 4913x the speed of light, which makes interstellar travel much easier.

That would mean her potential is.. ridiculous. If all the orbs follow that sort of progression (and why wouldnt they), they would be one of the most dangerous things in the universe. ]]>

You calculated double MJ, KE is m(v^2)/2, and then you didn’t convert into TNT equivalent energy.

… Let me double check that just to be sure

100 lbs (~45kg) at 5.3 km/sec

637 MJ…. so I lost 5 MJ in my previous calculation.

1 metric ton of TNT packs 4.184 GJ

1 kg TNT packs 4.184MJ

152kg of TNT for 637 MJ

335.65ish pounds of TNT, so a multiplier of 3.3565ish. Crazy what 5MJ does.

Predicts for 45kg mass to 151kg TNT, so the multiplier holds up in metric and murrican.

for a 50kg protagonist however, we’re looking at ~110 lbs, so…

~700.778 MJ KE

~167.49 kg TNT

multiplier predicts 167.825 so, within my margins of error, anyway.
