# 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)
