Question

A grandfather clock uses energy stored in raised weights. The weights transfer
energy to the clock mechanism as they fall. One clock has a 4.5 kg weight that
supplies energy to the chimes (which play a few notes every 15 minutes), and two
3.5 kg weights that power the clock and the mechanism that strikes the hours.
a Calculate how much energy is stored when all three of these weights are raised by 70 cm
