A ball moving translationally collides elastically with another , stationary identical ball. At the moment of impact the angle between the straight line passing the centres of the balls and the direction of the initial motion of the striking ball is equal to phi. Assuming that balls to be smooth find the fraction of the kinetic of the striking ball that is stored as the deformation potential energy at the moment of maximum deformation.

1.	A ball moving translationally collides elastically with another , stationary identical ball. At the moment of impact the angle between the straight line passing the centres of the balls and the direction of the initial motion of the striking ball is equal to phi. Assuming that balls to be smooth find the fraction of the kinetic of the striking ball that is stored as the deformation potential energy at the moment of maximum deformation.
