It's basically this problem, right?
a is the acceleration that the gravity exercises upon the bear, s is spatum/distance from top of the cliff to bottom. v0 is initial velocity and v is end velocity. t is the time it takes the bear to reach the ground when he jumps off the cliff. As you said... every of these informations is already available.
From physics, we know that
s = v0*t+(g*t^2)/2
-> g = (2*s-2v0*t)/(t^2)
Now that we know what the gravitational acceleration is, we can also find out the location.
North Pole g: 9.832 m/s^2
Equatorial g: 9.780 m/s^2
Most bears live in the zone between north pole and equator, that means, in that case, the g is somewhere in between the north pole g and the equatorial g, but only the polar bear lives at the north pole. So depending on the input values we either get g=9.832 or something in between 9.780-9.832. I guess with given values, it's much closer to 9.832, which ultimately makes the bear white, otherwise it'd be hard to distinguish between the brown, grizzly and the black bear, because all of them live in the vicinity of similar latitudes.
**I see you already figured this one out
Concerning Newton and Tesla: Being a polymath back then was outstanding, but by today's standards, it would be impossible. Nowadays, everything's so specialized, you can't be a biomed expert, a top mathematician plus a renowned painter at the same time. Tesla was, in a way, a polymath, too. He was very good at math and physics, had some fantastic insights into electricity, knew many languages (Serbo-Croatian, Latin, Italian, French, German, and English) and was very much into literature, be it goethe or twain (the latter even being a very good friend of his). But what really sets Tesla apart, in my opinion, is that he was first and foremost an engineer, meaning someone who could put his ideas into reality. Many don't see how hard it is to make reality out of theory. Sure, Newton was great, but it was all theory, and it's good. But being a theoretical genius plus proving your genius with real life applications, that to this day remain used, is something that very few scientists throughout history can claim. For me, Tesla is the biggest genius. But everyone is entitled to their own opinion.
