A bag of sand of mass 9.8 kg is suspended by a rope. A bullet of 200 g travelling with speed 10 ms -1 gets embedded in it, then loss of kinetic energy will be
Text Solution
Verified by ExpertsThe correct answer is:
B
P i = P f (no any external force)
0.2 x 10= 10 x v
v = 0.2 m/sec
Loss in K.E.= 
=9.8J
