steam-powered catapult used to launch aircraft could "throw a nissan pick-up five miles(8045meters)"

catapult has the power to accelerate 30-ton aircraft from zero to 160mph(71.511m/s) in just 2.5 seconds

nissan pick up truck weighs 3500 pounds and the flight deck is 57 feet off the water

assuming no air resistance for the truck how do i find the actual distance the catapult hurls the truck?

ive found that

initial V = 0m/s

final V = 71.511m/s

acceleration = 28.604m/s^2

and im stuck there

it also saids something about length of the deck but the value isnt given...

plz give me a clue on what to do next
