yeah for the trust question...this is wat i did.......since it said tht 0.5m was horizontal (frm cd to a) and 0.5m was vertical....that meant the angle CDA was 450 so i did (T for Thrust)....Tsin45 x 0.5 = 3g x .75 and then solved for T....not sure whether it was right :-\
LooL ya the centre of mass was sooo cool...i mean i was freakin out that they might give sum wierd shape that ive never even seen b4 in my life...and they ended up givin a rectange with a triangle...LoL how easy cud that get ! ;)
