Can any object have momentum even if its mechanical energy is 0? explain.
yes i can explain this theoritically as
let a body has both P.E and K.E & P.E = - K.E . then totol mechanical energy =K.E +P.E =0
but momentum is there as body is having some velocity in this case
but i am not sure if it is practically possible or not as there is no such example striking me right now
