Hestia (gray) and Hecate (black) just aren't getting the concept...
Greetings Lovely Students,
Please recall that Fnet = mass x acceleration and it is, typically, your task to resolve all the internal forces.
Remember that x and y are always perpendicular to each other so right angle trigonometry will be helpful when figuring out what is happening the in x direction and in the y direction.
As questions arise please let me know.
Sincerely, Ms. LaBrash
