Answer 2

a change in **** tends to refer to the slope of a line; a derivative

Answer 3

if i recall the setup: p = mv right?

Answer 4

im pretty sure im just not sure what the answer is i thought it was answer B but im not for sure :P

Answer 5

you're saying

Force x time = mv2 - mv1

Answer 6

F = ma

F = m \(\Large \frac{\Delta v}{t}\)

Ft = m \( \Delta v\)

Answer 7

im still confused o.O

Answer 8

what is the confusion?

Answer 9

well i dont really get the change in an object s momentum would equal to

Answer 10

momentum changes when velocity changes

change in momentum = m(v1-v2) = m \(\Delta v\)

Answer 11

using Newtons second law, we can equate F with a change in momentum

Answer 13

so i know its not B its not so would it be D ?

Answer 14

.... force(time) = mass(change in velocity)

force(time) = change in momentum

Answer 15

just trying to show how we get to b, as opposed to just say that it is b :/

Answer 16

okay thank you for the help :)

Answer 17

good luck ;)
