Two balls are moving on the same smooth horizontal plane. Their velocity components along one adge of the square plane are `10sqrt(3)m//s` & `20 m//s` respectively. Their velocity components along a perpenficular edge are `30 m//s` & `20 m//s`. Find the angle between their directions of motion.

Two balls are rolling on a flat surface. One has velocity components m//s and sqrt(3) m//s along the rectangular axes x and y , respectively and the other has component 2 m//s and 2 m//s , respectively. If both the balls start moving from the same point, the angle between their directions of motion is
