I think is altitude because tbh it don’t even mean nothing
Multiply the power (1,800 watts) by time (1,200 seconds) to get 2,160,000 joules (or 2.16 MJ)
When ball is about to hit the ground, almost all its potential energy has already converted into kinetic energy. Thus at t=0.9 sec, it has least potential energy.

You can find the emf of the battery by using:
Q = CV.
Q = Charge in capacitor plates = 30μC
C = Capacitance of the capacitor = 30μF
V = Q/C = 30/30 = 1V
Ans: The emf of the battery = 1V.
