Basically, what I'm asking is: "Is China really opposite the U.S. in the world? And if not, who is (or where is it)?" I'm just curious, thanks!

At a carnival, you can try to ring a bell by striking a target with a 9.00-kg hammer. In response, a 0.400-kg metal piece is sent upward toward the bell, which is 5.00 m above. Suppose that 25.0% of the hammer's kinetic energy is used to do the work of sending the metal piece upward. How fast must the hammer be moving when it strikes the target so that the bell just barely rings?

Please show your work with all formulas used. (conservation of energy formula I believe)
Show your answer in terms of the variables given and a numerical answer.

Thanks.

I'm a junior in a college calculus class. The following problem
was assigned, but the next day, after no one had completed it,
our professor attempted to do it but quit after 25 minutes.

Find the equation of the line tangent to the ellipse
b^2*x^2 + a^2*y^2 = a^2*b^2
in the first quadrant that forms with the coordinate axes
the triangle of smallest possible area
(a & b are positive constants)
