Onservative forces are present, does all of the energy in a system remain in a usable form?
5. When non-conservative forces are present, does all of
Explain.
6. What type of force are the force of gravity and the force exerted by a spring? How does this type of force
influence the energy in a system?
7. As an object falls to the ground, what happens to its energy? Ignore air resistance in this scenario.
8. If air resistance acts on a falling object, will all of its potential energy be converted into kinetic energy?

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
