Isn't Fn the equal but opposite force opposing the force of gravity, meaning it is directed upwards along with the upward force created by the rope?

Why do you subtract 43 from Fn instead of adding? Arent both forces moving in the same direction?

I think I found it: since the object is at constant velocity, the acceleration is 0, so Fnet= 10 (0) = 0 So Fk = 25 (Fnet=Fx-Fk) and then muK = 25/Fn. I realize that, in my drawing, I accidentally subtracted from Fn instead of adding to it, so Fn is 141. muK = 25/141 = .18

Or, do you have to find the accelerations of the blocks separately at first?

Homework Statement The surfaces of two blocks are roughened so that they do not slide against each other when a force of 30N is applied to the bottom block. 1.Find the force of friction between the two blocks. 2. Find the minimum coefficient of friction needed between the two blocks so that...

It will stay at that velocity unless something acts upon it with net force?

It will stay at that velocity unless something acts upon it with net force?

Homework Statement A child is pulling a 10kg sled along a horizontal plane of ice with a force of 50N directed 60 degrees north of east. Find the force of friction between the ice and the sled, given that the sled is moving at a constant velocity. Homework Equations Fnet = ma Fnet = Fx - Fk...
