17N.2.HL.TZ0.2f.ii
There is a proposal to power a space satellite X as it orbits the Earth. In this model, X is connected by an electronically-conducting cable to another smaller satellite Y.
The cable acts as a spring. Satellite Y has a mass m of 3.5 x 102 kg. Under certain circumstances, satellite Y will perform simple harmonic motion (SHM) with a period T of 5.2 s.
(f.ii)
Describe the energy changes in the satellite Y-cable system during one cycle of the oscillation.

Ep in the cable/system transfers to Ek of Y
and back again twice in each cycle
Exclusive use of gravitational potential energy negates MP1
