kinetic energy question

1. The problem statement, all variables and given/known data
I don’t know how to solve this question.

28.8J of work were done in accelerating a mall of 1.8 kg from rest. Find its final velocity. I’m not sure which formula to use..

2. Relevant equations
F=ma
W=Fs
KE=1/2 mv^2

3. The attempt at a solution
I can’t figure out which formula to use. (did some working in my workbook)
