Projectile motion off a cliff

[Drrrrrr. Celty]

Is there a way to quickly solve this type of problem? It seems like the only effective method is through quadratic equation. Or should we assume that all projectile motion problems would be from a y of 0?

I mean for example in TBR book example 1.15. Sounds wayy too complicated.

The next page has the "Turbo" method. they show you the quadratic way first so you appreciate the turbo method more..... at least in theory 😛

I always broke it into two parts. From start to apex, then apex to ground. Apex to ground is free fall, so that's easy.

So basically you take the first half to add the height to previous cliff height and then plug that back into the Yo = 1/2 aT2?

Yes. I think you both are saying the same thing.

That was impressively easier than what I expected.
