Acantilever can be considered as a mass, spring, damper system.

(a) is this a first, second, or third order system, and why? list the energy storage elements and associated energy storage mechanisms.
(b) assuming the system is underdamped, what output would you expect from this system when subject to a step input? roughly sketch your answer

Alarge cruise ship of mass 7.00 ✕ 107 kg has a speed of 11.6 m/s at some instant. (a) what is the ship's kinetic energy at this time? (b) how much work is required to stop it? (give the work done on the ship. include the sign of the value in your answer.) (c) what is the magnitude of the constant force required to stop it as it undergoes a displacement of 3.00 km?
