Note 3 key dates in blood spatter history and what those dates mean to evidence today.

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2

the answer for apex is the lowest

reserve is the answer

if the person is shown to have +90n, then ans is -10n.

if the person is shown to have -90n, then ans is +10n.
