I have a follow-up to my question at 4:10 about work because I still can't figure it out.

F-F(friction)=ma
F-F(friction)=2*3
F-2.5=2*3
F=2*3 + 2.5
W=Fd
W=(2*3 + 2.5)4
Distributing the "4" I get
W=2*3*4 +2.5*4
Please help in pointing out where I have gone wrong. Thanks

    You are correct, that is right. I typed the distance wrong on the friction term.
