A body can have mechanical energy without having _____________.a) Kine

1.	A body can have mechanical energy without having _____________.a) Kinetic energyb) Potential energyc) Both a and bd) None of these
Answer» EXPLANATION: Since, mechanical ENERGY is the sum of kinetic energy and potential energy. And as given that, momentum of the body is zero, it MEANS velocity of the body is zero, so it has kinetic energy equals to zero. ... So, EVEN if the momentum of the body is zero, it may have mechanical energy.
