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?
W=Fd
F=ma
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?
