What is the potential energy of a 100 g car sitting at the top of a 1m hill?

How do we measure or think of speed in the united states?

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

Match each scenario to the form of energy it represents
