#how do we know
soft rampart
for A
how do we know its 12/13kmg-T=kma
I done T-12/13kmg=kma
because obviously if T is greater than 13/13kmg it will go up
soft rampart
Write eq motion of b first
yeah b is T-3mg=3ma

Then surely u should know a can’t start with T

Then surely u should know a can’t start with T
not always i.e

Yeah
Look
B is heavier
B will go down A will go up
For B it’s W-T…
For A it’s T-Wcosx …

pulsar nest
not always i.e
it always says whether its moving up or down the plane like here it says A is moving up the plane

it always says whether its moving up or down the plane like here it says A is mo...
so we assume B is moving down right
soft rampart
thats how a pulley works
yeah ik but like they havent explicity told us which is why I was sceptical
soft rampart
they said A is moving up the plane
yeah ik
