A bomb of mass `6kg` initially at rest explodes in to three identical fragments On of the fragments moves with a velocity of `10sqrt3 hatim//s` another frament moves with a velocity of `10 hatj m//s` then the thired fragment moves with velocity of magnitude .

A cannon ball is fired with a velocity of 200 ms^(-1) at an angle of 60^(@) with the horizontal. At the highest point of its flight it explodes into 3 equal fragments. One fragment is going vertically upwards with a velocity of 100 m//s and second going vertically downwards with a velocity of 100 ms^(-1) the third fragment will be moving with a velocity of

A bomb initially at rest explodes by it self into three equal mass fragments. The velocities of two fragments are ( 3 hati + 2 hatj ) m/s and (–hati – 4 hatj ) m/s. The velocity of the third fragment is (in m/s)-

A shell of mass 20 kg at rest explodes into two fragments whose masses are in the ratio 2 : 3 . The smaller fragment moves with a velocity of 6 m//s . The kinetic energy of the larger fragment is
