Answer 2

kinematics eq 4

Answer 3

v^2=13+2(-2.1)

Answer 4

final velocity is already given (hint: the car is coming to a stop)

you are solving for distance

Answer 5

13=x+2(-2.1)

Answer 6

if the car is coming to a stop then what is the final velocity?

Answer 7

good, so set up the equation for delta x

Answer 8

0=13+2x

Answer 9

like that kind of?

Answer 10

v^2 = v_o ^2 + 2a*delta x

plug in everything except delta x and solve for delta x

Answer 11

0=13^2+2(-2.1)x

Answer 12

good, now solve for x

Answer 13

40.24

Answer 14

SO C

Answer 15

good
