Ahhhhhh it all make sense now. Sorry I was so dense previously. Thank you so much for your help this is an important concept I would have missed otherwise!
Hey so 146 N Is the answer which makes sense considering that this force is required to keep the box from moving, but why Is this not the value of my original calculations? Shouldn't the answer be the same whether evaluating the force of friction derived from the normal force and from the...
I understand this i was simply saying that the normal force is derived by splitting the gravitational force into two components: one perpendicular to the slope (which is equal to the normal force) and one parallel to the slope which i called the down-slope force (Granted this may be the...
Ah ok then I'm guessing that would not apply in this scenario as the boxes are moving together at constant velocity and this the acceleration of the boxes is 0?
When considering the FBD of the top box I include the following forces
-friction force
-gravitational force (two components are...
The string is attached to the bottom box, my mistake not including this initially.
So the magnitude of the frictional force will be affected by the force of the rope on the system?
Hello! I'm excited to join this physics community and appreciate any help that the people posting in this thread will give me!
The problem is this
You are lowering two boxes, one on top of the other, down the ramp with length 4.75m and height 2.5m (The ramp has its highest point at the right...
