A bomb of mass 12 kg explodes into two piece of masess 4 kg and 8kg . The velocity of mass 4 kg is 20 m/s . Find the velocity of mass 8 kg

Text Solution

Verified by Experts

Conversation of linear momentum :
Intial momentum of bomb = Sum of final momentum of fragments
` rArr 0 = 4 kg xx 20 m//s + 8 kg xx v `
` rArr v = (-20xx4)/8m//s = - 10 m//s `
