A ball falls from a shelf. Assuming there is no friction, why is the conservation of mechanical energy independent of mass?(1 point) The displacement of the ball is insignificant compared with Earth's size.

The mass of the ball is insignificant compared with the mass of Earth.

Mass is eliminated when equating elastic potential energy with kinetic energy.

Mass is eliminated when equating gravitational potential energy with kinetic energy.

It's B

Explanation:

Hope this helps, tell me if im wrong!

C

Explanation: Mass is eliminated when equating elastic potential energy with kinetic energy.

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
