An astronaut, while on the Earth, gives a good kick to a soccer ball. The ball lands in tę seconds after the kick. The astronaut then takes the ball to the Moon where she gives it a somewhat weaker kick. As a result, the ball reaches exactly the same maximal height it reached previously on the Earth. What statement is true about the time tm that the ball spent aloft on the Moon? (The gravity on th Moon is 6 times weaker than on the Earth. You can rely either on a direct calculation, or on a dimensional analysis or both)
A. tm=36 te
B. tm=12te
C. tm=te
D. tm=(6)^1/2 te
Е. tm=6te

Suppose that f : rn → rm and that a ∈ k, where k is a connected subset of rn . suppose further that for each x ∈ k there exists a δx > 0 such that f(x) = f(y) for all y ∈ bδx (x). prove that f is constant on k; that is, f(x) = f(a) for all x ∈ k
