Best ResponseYou've already chosen the best response.1So the next step is to isolate the object and put all forces that are applied TO the body.

Best ResponseYou've already chosen the best response.1According your your FBD, "TMg cos 60 =Ma" is not correct.

Best ResponseYou've already chosen the best response.1dw:1358007244777:dw So you have two unknowns (T and a) and two equations. :)

Best ResponseYou've already chosen the best response.0ok so i got mgsin 30mgsin 60=ma+ma

Best ResponseYou've already chosen the best response.0m=5kg for both i got a=1.830 which is wrong

Best ResponseYou've already chosen the best response.1Your equation assumed that the masses accelerate DOWN the 30 deg. plane, so a<0 is correct! :)

Best ResponseYou've already chosen the best response.1It is logical that the masses slide down the 60 deg. plane. So put mg sin(60)T = ma , and Tmg sin(30) = ma This assumes mgsin(60)>T (=> a>0) and T>mg sin(30) , again => a>0

Best ResponseYou've already chosen the best response.0so what ur doing is making accelration + right

Best ResponseYou've already chosen the best response.1You don't always have to guess the direction right the first time. Make a reasonable guess, using logic, and if it comes out negative, reexamine to see if it is logical, or if you made a mistake. This is how scientiests work: examine the work when there is a surprise.
