A grenade having mass of 10 kg flying horizontally with a velocity of 10 m/s explodes into two fragments. The larger fragment has a velocity of 25 m/s in the direction of the intial velocity of the grenade. The smaller fragment has a velocity of 12.5 m/s in the opposite dirction. The masses of the fragments are
