1.	A 7 kg shell kept at rest suddenly splits up into three parts. If two parts of mass 3 kg each are found flying due north and cast with a velocity of 3 m/s each, what is the velocity of the third part after explosion ?
Answer» 9 m/s DUE north-east `(9)/(SQRT(2))`m/s due south-east ` 9 sqrt(2)` m/s due south-west `9 sqrt(2)` m/s due south-east Solution :` 9 sqrt(2)` m/s due south-west
