A mass suspended from the lower end of a spring moves up and down repeatedly. At which positions in the motion of the mass do the gravitational potential energy of the mass (GPE), the elastic potential energy in the spring (EPE) and the kinetic energy of the mass (KE) reach their maximum values?
- AGPE: bottom, EPE: middle, KE: top
- BGPE: bottom, EPE: top, KE: middle
- CGPE: top, EPE: bottom, KE: middle
- DGPE: top, EPE: bottom, KE: top
