A piano is brought upstairs by two workers. Due to a mistake by one of the workers, the piano rolls down the stairs and finally comes to rest by the outside door. Which sequence best describes the energy transformations for the piano from the moment it is being brought upstairs to when it stops by the door? A. Potential energy -> Kinetic energy -> thermal energy of the ground and piano B. Ground energy -> Potential Energy -> Thermal energy -> kinetic energy of the piano C. PE -> KE -> PE -> TE of the piano and ground D. KE -> PE -> KE
