During the head on collision of two masses of 1 kg and 2 kg , the maximum energy of deformation is 
. If before collision, the masses are moving in the opposite direction, then their velocity of approach before the collision is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
When deformation is maximum, both the masses are moving with same velocity i.e., 
. So, applying momentum conservation, we have
………… (i)
Applying energy conservation, we have
