Answer:
Mechanical energy comprises of potential energy and kinetic energy. If the momentum of the object is zero, it means the velocity of the object is zero and an object is not moving. So, the kinetic energy of the object is zero.
But if the object is kept stationary at certain height then it will have potential energy. Therefore, an object can have mechanical energy even if its momentum is zero.
