Homework Help: Physics homework help

  1. Sep 17, 2007 #1
    A jet plane lands with a velocity of 101 meters/second and can accelerate at -5.1 meters/second2 when coming to a rest.

    a) Once it hits the runway, how long till it stops?

    b) Can this plane land on Gilligan’s Island if its runway is 0.80 x 109 μ meters long?

    2. Relevant equations

    v = v0 + at
    x − x0 = (1/2)(v0 + v)t
    x = x0 + v0t + (1/2)at^2

    3. The attempt at a solution

    I have no idea how to do this problem. I have had one physics class. Sorry guys. Your help would be great
