Homework Help: science

A jet plane lands with a speed of 110 m/s and can decelerate uniformly at a maximum rate of 5.7m/s^2 as it comes to rest.
Can this plane land at an airport where the runway is 0.91 km long?

I have to answer by Calculating...HELP!

Vf^2 = Vo^2 + 2ad = 0,
(110)^2 + 2 * (-5.7)d = 0,
12100 - 11.4d = 0,
-11.4d = -12100,

d = -12100 / -11.4 = 1061.4m = 1.061km.

NO, the runway is too short
