Momentum and CollisionHard
Question
A bag of mass M hangs a long thread and a bullet (mass m) comes horizontally with velocity v and gets caught in the bag. Then for the combed system (bag + bullet) :
Options
A.Momentum is mMv/(M + m)
B.kinetic energy is (1/2) Mv2
C.Momentum is mv
D.kinetic energy is m2v2/2(M + m)
Solution
COLM : mu + 0 = (m + M)v ⇒ v = 
KE after collision =
(m + M) × 
u2 = 
KE after collision =
(m + M) × u2 = Create a free account to view solution
