A 6.1 kg sphere moving at 2.2 m/s elastically strikes another 6.1 kg sphere at rest in such a way that the first one goes off with a momentum of 9.97 kg·m/s at an angle of 42° to its original path. a) At what angle to the original path does the second one go off? b) What was the original momentum of the system? c ) What is the velocity of the first sphere after the collision? d ) What is the momentum of the second sphere after the collision? e ) What is the velocity of the second sphere after the collision?
