so here r ma doubts
=> it is sometimes heard tat inertial frame of referance is only an ideal concept and no such inertial frame exists.comment.
=>the accelaration of a particle is zero as measured from an inertial frame of referance . can we conclude tat no force acts on it?
=> a...
taking the man n the platform to b inna system, there is no external horizontal force on the system, the linear momentum remians constant. thus
(M+m)18 = MV- mv...now solve n check
usually i get ma equations in variables n thn substitute the values...suppose the man moves at a speed w towards left and the platform recoils at a speed V towards right...hence the speed of the man relative to the platform is V+w=v...or w= v-V...
yea...tats wht ma proff always says...russians r gud at three things...chess, math n sipping vodka..lol...he is also v fond of hungarian probs...tho i liv in india, while training for math olympiad hungarian n russian n a bito korean probs were most discussed, altho i personally find russian...
ouch , i cud get this in like another 20 hrs, I am sorry, ma heads got too heavy wit sleep to think, ...im j.purpleink@gmail.com...well, don't worry too much...gud nite
so i hope u can wait till tomorrow...ill get u the answer...giime ur is where i can mail, or udder way to contact...ill do my best...i got to leave for a snooze now
wow, ok...so according to me , u need to b familiar wit loc n e n all, but if they r giving a prob at ur level, witout the knowledge of dis, they probably expect u to manage witout loc...so basiclly by blabaring more, ill only confuse u more n nothing else...but if u want, ill ask ma proff...
