A velocity of `10 ms^(-1)` has its Y-component `5sqrt(2)ms^(-1)`. Calculate its X-component.

Two billiard balls are rolling on a flat table. One has the velocity components v_(x) = 1 ms^(-1), v_(y) = sqrt(3)ms^(-1) and the other has components v'_(x) = 2ms^(-1) and v'_(y) = 2ms^(-1) . If both the balls start moving from the same point, what is the angle between their paths ?
