Physics - 16.5 Simple Harmonic Motion - 2 Springs (3 of 5) 2 Unequal Springs, 1 Mass

In this video I will find v(x)=?, a(x)=?, w0=? of a block attached to 2 springs (with 2 different spring constants) which are attached to a ceiling.

Next video can be seen at:

i meant the acceleration should be -omega square x?

[Catcouture]

physics 3a- I think omega should be squared when relating it to acceleration. Is your work correct?

Why is gravitational potential energy ignored? Shouldn't we also add it to total energy, because height changes?
