1. The problem statement, all variables and given/Information If a person pushes a 28 kg object 1.2 m, how much work did they just do? 2. Relevant equations W=Fd F=ma 3. The attempt at a solution If W=Fd and F=ma, then W=(ma)d. The farthest I can get is W=28a*1.2=33.6a. Since the motion is horizontal, a=9.8 m/s2 wouldn't apply, so I am left with 2 variables and no answer. However, the correct answer is 1200 J. Where is this answer coming from?
