Calculating Landing Distance on an Aircraft Carrier

[bigzee20]

Homework Statement

A plane lands with a velocity of 111.1 m /s and accelerates at a maximum rate of -6.8 m/s^2
Fom the instant the plane touches the runway, what is the minimum time needed before it can come to rest.
Part 2 the plane is landing on a naval aircraft carrier that is 0.80km long. What distance does the plane require to land answer in units of km.

Ok i managed to get the first part using t = Vf-Vi /a. Which is 16.33sec

Now the second part i know i got to change km to m but i can't figure out what else to do.
Can someone help me

You need to use a kinematic equation that involves distance. You know everything you need to solve for it.

WOOT! Nice i got d=Vit+1/2a(t)^2
0.90km gracias mate
