A body of mass 2 kg moving with a velocity 3 m/s collides with a body of mass 1 kg moving with a velocity of 4 m/s in opposite direction. Ifthe collision is head on and completely inelastic, then 

a) 
Both particles move together with velocity (2/3) m/s 
b) 
The momentum of system is 2 kg m/s throughout 
c) 
The momentum of system is 10 kg m/s 
d) 
The loss of KE of system is (49/3)J
