1.	A particle of mass m having collided a stationary particle of mass M deviated by an angle pi//2 whereas the particle M recoiled at an angle theta = 30^(@)to the direction of the initial motion of the particle m. How much in percent and in what way has the kinetic energy of this system changed after the collision, if M/m = 5 ?
