thank you very much :smile:.
so b and d are both negative in both the ihat and jhat value. can i put those in the third quadrant?
question a is prompting for what vector operations could result in -38 units^2. so am i supposed to use the i hat as an imaginary number? i can't think...
I'm sure this is quite simple, but I don't understand the notation. This is from a supplemental book that we have to do outside of class--there isn't a matching textbook and I really don't understand what they want here.
I noticed that if i square...
Thanks again. So it was the first way. I was able to do several more problems given that information.
One of my big mistakes was not realizing that one box could be involved in multiple action-reaction pairs. I was trying to balance the boxes on both sides as well as the ropes which...
I'm sorry. I am so confused.
Trying again here--I editted the picture.
I have checked all the definitions again.
So in the gray box we have this rope. The acceleration of the 2block/1box unit is 2a. The mass of the 2 blocks is 2 each.
The force on the rope B is 4ma.
Thank you both for your answers. It is so kind of you to spend time helping confused students. I truly appreciate what you are doing here.
I am attaching a scan of the question for clarification. I hope the question I asked earlier matches the picture. If not, could you please tell me how...
This isn't a joke, I really don't know if this is right or wrong. Please let me know if this is wrong so I can learn what I am not getting right.
Three different sets of boxes are being pulled along frictionless surfaces attached to a rope that ends with the rightmost box...
