1.	Can you object have momentum even if its mechanical energy is zero? Explain .
Answer» Yes i can explain this theoritically asLet a body has both P.E and K.E & P.E = - K.E . then totol mechanical energy =K.E +P.E =0But momentum is there as body is having some velocity in this caseBut i am not sure if it is practically possible or not as there is no such example striking me right now.
