Question

A body initially at rest explodes suddenly into three equal parts.The momenta of two part

Answer 1

ACCORDING TO LAW OF CONSERVATION OF LINEAR MOMENTUM  

M1V1=mv+mv+3mv

v=30ms-1

30kg*0=30m+30m+3xm

assuming masses m,m and 3m and x=velocity of hevier fragment

o=60m+3xm

-60m/3m=x

-20=x

THEREFORE THE HEVIER FRAGMENT FLIES OFF WITH A SPEED OF 20ms-1 in the perpendicular direction.

plz approve.....!!

Thank you.
