   what would happen if you're swimming underwater and a small tuna (~15 lbs.) hits you at full speed (~45 mph)?

     @GrungeQueef If it wasn't for GNU units converting to sane units for us, the braindead units would make it too hard to calculate.
     
     45 mph == 72.42048 kph == 20.56384 metres / second
     15 lbs == 6.8038856 kg
     
     With assumptions, the calculation is; (15 lbs)(20.56384 m^2 / s^2) / (5 cm) (due to the water, we take a shortcut and ignore the immediate impact force and assume that the impact force is spread over 5 cm of movement due to the water).
     
     That works out to be 2798.2803 Newtons of force, or 285.34518 kgf, which I reckon could give you a concussion if you get hit in the head, or a large bruise if you get hit in the torso - but most likely you won't die if you don't end up drowning.
     
     There's a high chance I got the calculation wrong, so anyone is free to interject with the correct one.

     @GrungeQueef There's no point watching the video, as obviously the acrylic has µm of give, while the body of a tuna has like 1cm of give.
     
     (15 lbs)(20.56384 m^2 / s^2) / (1 cm) == 13991.401 N == 1426.7259 kgf

     @Suiseiseki here's a video of a tuna crashing into the glass at an aquarium and instantly dying.
