Aball is thrown vertically into the air and when it returns after an interval of 2 seconds, it is caught. which one of the following statements is true if the acceleration due to gravity is 10 m/s/s and air resistance can be neglected?
the acceleration at the top of its flight is 10 m/s/s upwards.
the acceleration at the top of its flight is 0 m/s/s.
the time taken for the descending motion does not equal the time taken for the ascending motion.
the acceleration after it leaves the hand is 10 m/s/s downwards.

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
