teta=tan^-1(.3) teta=16.70 sine law: T/sin53=136.08/sin36.87 T=181 B:: teta=tan^-1(.4) teta=21.80is this right? T/sine36.87=90.72/sine53.13 T=68.04

last attempt to try .. hihi

for A: T-m1gsin53.13-μkm1gcos53.13=m1a m1g-T=m2a (T-1065.5)/136.08=a (1334.94-T)=90.72a T=1227.4 a=1.19 hehe! I am trying .. my memory is low :)

For B Fmax=0.4(90.72)cos36.78 Fmax=21.77 T=90.72sin36.87 T=1177.20 is this right?

for block A Fmax=0.30(136.08)cos53.13 Fmax=24.5 T=300(9,81)sin53.13 T=2354.4

for A: T1=136.08sin53.13/sin36.87 B: T2=90.72sin36.87/sin53.13 maybe il copy later I am weak .. grr! sorry sir thnx for intertaining

sory I am weak here in physics .. hihi! this? μm1g-T1=m1a1 m2gsin(teta)-T2=m2a2 so a=(g(μm1-m2))/m1+m2 last try .. hihihi sorry ..

i solve it again through dis solution.. so : T-m1gsin53.13-μkm1gcos53.13=m1a eq 1 T-505.44=90.72a eq2 T-m2gsin36.87-μkm2gcos36.87=m2a so T=577.27 a=-3.42for 2nd block: T-m2gsin36.87-μkm2gcos36.87=m2a eq 1 : T-505.50=90.72a T-m1gsin53.13=μkm1gcos53.13=m1a eq2 : T-1043.93=136.08a so...

i need to know if my formula is right or wrong? f wrong what part? or at beginning I am wrong ? what wod be the possible formula i used,,, thnx a lot

thnx .. block A = 136.08 kg B=90.72 kg i already draw the free body block A will fall and block be will go upward.. the motion going to left. what would be posible formula to use in this problem? are my solution right?

help me please ! I am confuse what would be the fomula i`l use

for A: Fmax=μk(m1)gcos53.13 54=μk(m1)gcos53.13 μk=0.03 T-300(9.81)sin53.13-μk(300)9.81cos53.13=(300)a eq(1) 200g-T=200a eq(2) subtitute (1) and (2) to find a a=-3.79 for block B: Fmax=μk(m2)gcos36.87 64=μk(m2)gcos36.87 μk=0.04 T-200(9.81)sin36.87-μk(200)9.81cos36.87=(200)a...
