${x}^{2}+{y}^{2}=4$ is the formula for a circle with radius 2.

The center is 0,0 and you can graph it to show that center bysolving the equation for y:

$y=\sqrt{4-{x}^{2}}$

And

$y=-\sqrt{4-{x}^{2}}$

It looks like a standard form

Standard form: Ax + By = C

in this case, you have x = a and b=y, leading to your weirdequation.

C/A = x-intercept = 4/x

C/B = y-intercept = 4/y

A movie stuntman (mass 80.0kg) stands on a window ledge 5.0 mabove the floor. Grabbing a rope attached to a chandelier, heswings down to grapple with the movie's villian (mass 70.0 kg), whois standing directly under the chandelier.(assume that thestuntman's center of mass moves downward 5.0 m. He releasesthe rope just as he reaches the villian).

a) with what speed do the entwined foes start to slide acrossthe floor?

b) if the coefficient of kinetic friction of their bodies withthe floor is 0.250, how far do they slide?
