A 5 kg stationary bomb explodes in three parts having mass 1:1:3 respectively. Parts having same mass move in perpendicular directions with velocities 30 m/s and 30 m/s. The velocity of the bigger part will be

A 5 kg stationary bomb is exploded in three parts having mass 1: 1: 3 respectively. Parts having same mass move in perpendicular direction with velocity 39 m/s, then the velocity of bigger part will be:

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 30 ms^(–1) , then the velocity of bigger part will be : -

A 5 kg stationary bomb is exploded in three parts masses 1 : 1 : 3 respectively. Parts having same mass move in perpendicular direction with the velocity 30 m/s. Then the velocity of the bigger part is

1 kg body explodes into three fragements. The ratio of their masses is 1 : 1: 3 . The fragments of same mass move perpendicular to each other with speed 30 m/s. The speed of heavier part is

Two bodies of masses 1 kg and 2 kg are moving in two perpendicular direction with velocities 1 m//s and 2 m//s as shown in figure. The velocity of the centre of mass (in magnitide) of the system will be :
