Physics question

[modern fern]

I don't understand how we can imply that the object is slowing down (the gravity's x-component + applied force could be equal to the friction)

No, I believe that because you can see that the vector up the incline is larger than the vector downward, we take it as a greater force, and thus giving the body negative acceleration.

I don’t think it’s necessary for it to be friction because it is nowhere mentioned so? I might be wrong, however.

vector's length scales with its magnitude

so friction > gravity that is pulling down

[modern fern]

doesn't it combine with the applied force in the x direction as well?

making it less certain

[hazy badge]

where is the applied force?

[modern fern]

there's four forces acting on it, the aplied should be the one opposite to the friction

[hazy badge]

yes

ok

that makes sense

[modern fern]

I think I kind of get it, I just think the image shouldv'e made it more obvious

thx

[hazy badge]

umm i think

it has to do with

the normal being equal to one of the component of gravity

sinc ethe block isnt movign perpendicular to the plane
