A person weighing 604.4 N is moving from the 1st to the 6th floor in a lift. As the lift approaches the the 6th floor, it decreases its upward speed from 8.8 ms-1 to 2.6 ms-1. in 2.5 s. What is the average force exerted by the lift floor on the person during this time? (Answer to 3 s.f. with no units)

I tried working out the acceleration and stuff but with all the calculations the answer i have gotten is wrong.
Any hints/clues?
