0 m/s = 155 m/s + (-31 m/s^2) * t<br />
-155 m/s = (-31 m/s^2) * t<br />
155 m/s = t<br />
(-31 m/s^2)<br />
5 s = t <br />
t = 5.0 x 10^1 s<br />
b) d = v i + v f * t<br />

v initial = 55 m/s<br />
v final = 0m/s<br />
t = 5.0 s<br />
d = (155m/s) + (0 m/s) * 5.0 s<br />
2<br />
d= (155 m/s) * 5.0 s<br />
