ohhh. I see what I did wrong, thanks! You're great help! I can't believe my mistake!

Hm? Don't you need to? Fg=mg so Fg=(9.1)(9.8), and normal force is going the other direction and Fnet=0, so normal force is also 89.18. Isn't that right?

a) A block weighing 9.1N requires a force of 2.8N to push it along at constant velocity. What is the coefficient of friction for the surface? b) A weight "W" is now place on the the block and 8N is needed to push them both at constant velocity. What is weight "W" on the block? This is what I...
