**bobpursley**, Thursday, April 8, 2010 at 11:12amThe initial momentum is zero, so the final vector momentum is zero. You have the positions, dividing by time t means velocity.

in the x:

0=1/3 40/t + 1/3 20/t + 1/3 x/t

multipy both sides by t, solve for x.

in the y:

0=1/3 0 + 1/3 (-60/t) + 1/3 y/t

solve for y.

you have x,y coordinate of the third piece at that time t.
