Question

Modern oil tankers weigh over a half-million tons and have lengths of up to one-fourth mile. Such massive ships require a distance of 4.5 km (about 2.8 mi) and a time of 17 min to come to a stop from a top speed of 32 km/h.

(a) What is the magnitude of such a ship's average acceleration in m/s2 in coming to a stop?

(b) What is the magnitude of the ship's average velocity in m/s?
