Open Question: Help with a forces question (Physics)?

Well, the first thing we want to do is find the block's acceleration:
F = ma
5 N = 2kg*a
2.5 m/s/s = a
F = ma
5 N = 2kg*a
2.5 m/s/s = a
So, if the block is slowing down by 2.5 m/s each second, the time it takes to come to rest from 10 m/s is 4s.
