Who are the scientist that study past people, how they lived and the cultural practices they shared?

a. formula: f=ma or f/m=a

10,000n/1,267kg≈7.9m/

b. formula: a= and s=d/t

speed= 394.6/15

s=26.3m/s

a=

a=1.75m/

c. 7.9-1.75=difference of 6.15m/

d. the force that most likely caused this difference is friction forces

well, there are a lot of places we get information about earth from. like science classes, websites, books, newspapers, etc.
