yep Y will reach first .......................... u guys ar rite ............................................

cuz if u notice gcos@ is removed by the plane so the primary accn. is mg sin @ ....... so the

vertical component is gsin@cos@ ad opposed to g for Y .....................

sorry ppl for postin such a stupid question[if and only if it wasted ur time [3]]..............

no...

theres a component of normal reaction on block in upward direction also..

so g-N's component/m is vertical acceleration..

ohh yess....why i asked that stupid question...............

Straight line is shortest distance in 2 dimension so.......Y will reach first....

even if wedge is moving...then also X traces some curve which wont be straight line........
