A mass fixed to the bottom end of a spring oscillates vertically. At which positions in the mass’s motion do the gravitational potential energy of the mass (GPE), the elastic potential energy stored in the spring (EPE) and the kinetic energy of the mass (KE) each 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
