oooh sorry no, hmm that could be right because they didnt really give any direction to where the couch is going, but i kinda assumed that its moving forward so there won't be any displacement in the verticle direction?

hmmm it means that its moving at a constant velocity. ooh okay yes that makes sense thank you! :D

Homework Statement if we apply a force of 56 n on 40 degree angle above the horizontal than how would the results compare if it was applied 40 degree below the horizontal?Homework Equations none The Attempt at a Solution i said that it would be the same and different depending on how we look...

hi i was wondering how would the results be different if we were to apply a force below the horizontal at a certain angle rather than above the horizontal.

well this would mean that the acceleration is 0 so there is no acceleration? but i don't think that is right

ooh sorry, okay i broke down the fa into its components which i get fapph=56cos40 fapph=42.9 fappv=56sin40 fappv=36.0 then i found the fg to be 804.42 fg=mg fg=(82)(9.81) fg= 804.42 then i solved for fn by making fnet = 0 because the forces cancel out because there is no movement in the...

Homework Statement An 82 kg couch is being pushed with a force of 56 N at an angle of 40 above horizontal. If the coefficient of friction between the couch and the floor is 0.051, what is the acceleration of the couch? Homework Equations The Attempt at a Solution
