The first one is me :( , uglyy
this is my sister

kiss him because she will be happy

naw u ain’t ugly and yo sister she look like a bobble head in that photo

Explanation:

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

~kinetic ~potential

explanation:

kinetic and potential energies would be types of mechanical energies.
