because it equals 322.5 which is rounded to 323

Vocaloid:
F = ma
F = m(delta v/t) since acceleration is equal to delta v/t
Ft = m*deltaV by multiplying both sides by t
so impulse = Ft = m* delta v = ?

Vocaloid:
"delta" means change, or in this case, final velocity - initial velocity

Vocaloid:
remember that momentum is mv
an increase in momentum (8000) is m*deltav
so impulse = Ft = m* delta v = 8000 (D)

Vocaloid:
Hm... since change in momentum is just m * deltav it should actually be the same regardless of whether you're wearing kneepads or not , so I will hesitantly say D but I'm going to double check w/ sillybilly @sillybilly123
