A ball falls from a shelf. Assuming there is no friction, why is the conservation of mechanical energy independent of mass?(1 point)
Responses
a The displacement of the ball is insignificant compared with Earth's size.
b Mass is eliminated when equating gravitational potential energy with kinetic energy.
c The mass of the ball is insignificant compared with the mass of Earth.
d Mass is eliminated when equating elastic potential energy with kinetic energy.
