A 0.372 kg bead slides on a straight frictionless wire with a velocity of 3.38 cm/s to the
right, as shown. The bead collides with a
larger 0.689 kg bead initially at rest. After
the collision, the smaller bead moves to the
left with a velocity of 0.65 cm/s.
Find the distance the larger bead moves
along the wire in the first 5.2 s following the
collision.
Answer in units of cm

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

Atypical jetliner lands at a speed of 146 mi/h and decelerates at the rate of (10.4 mi/h)/s. if the jetliner travels at a constant speed of 146 mi/h for 1.5 s after landing before applying the brakes, what is the total displacement of the jetliner between touchdown on the runway and coming to rest?
