☸the heavier mass will move with less velocity than the lighter one...
☸this is because of CONSERVATION OF MOMENTUM
☸so.. here... the momentum of body before explosions is 0 kg m/s .... because initially the body is at rest and --- > >momentum=mv=m(0)=0kgm/s
▶so after explosion the total momentum must be the same as the initial momentum
_______________________________
let M>m {masses of the parts of body after explosion}
=> M=mass of heavier part
=> v2 = velocity of heavier part
=>m=mass of lighter part
=> v1=velocity of lighter part
______________________________
=> 0=mv1+Mv2
=> mv1=Mv2{magnitude}
➡ as M>m
➡ V1>v2
hence the lighter part will move with greater velocity....
hope it helps you...☺☺
