Three particles start from origin at the same time: one with velocity v_(1) along positive x - axis, the second along the positive y-axis with a velocity v_(2) and the third along the line y=x with such a speed that all the three always stay in a straight line, then the velocity of the third particle is (sqrt(k) V_(1)V_(2))/((V_(1)+V_(2))) .
