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

An astronaut in space cannot use a scale or balance to weigh objects because there is no gravity. but she does have devices to measure distance and time accurately. she knows her own mass is 77.4 kg , but she is unsure of the mass of a large gas canister in the airless rocket. when this canister is approaching her at 3.50 m/s , she pushes against it, which slows it down to 1.30 m/s (but does not reverse it) and gives her a speed of 2.60 m/s . what is the mass of the canister?
