Answer 1

find the acceleration first..

Answer 2

And thats by getting the final velocity minus the initial velocity over time right?

Answer 3

yes...good...

Answer 4

which ones the final velocity?.-.

Answer 5

20 m/s

Answer 6

Will it be 4?

Answer 7

yes....

Answer 8

Okay then from there i look for acceleration?

Answer 9

you know the mass...now you know the acceleration...find the force

Answer 10

4.8 x 10^3 newtons?

Answer 11

yeah...!!!

Answer 12

Yess! Thanks :)
