A 1 kg stationary bomb is exploded in three parts having mass 1 : 1 : 3 respectively. Parts having same mass move in perpendicular direction with velocity , then the velocity of bigger part will be : -

Answer: (1)

Solution

Let the masses be . The bomb was at rest, so the total momentum after the explosion is zero. The two equal parts (each ) fly off perpendicular to each other at , so the
