    Movement
In summary, the problem involves a harmonic system with 4 degrees of freedom, including roll, sway, and heave movements. It is not clear what is depicted in the figure, but assumptions can be made for the solution.

You have all the freedom to make any assumption to solve the problem. All 3 kinds of movement must be considered (roll, sway, heave). Variables are up to you.

The Attempt at a Solution



I tried to solve it by considering it an harmonic system.

It is not clear what is depicted in the upper right part of the figure. Is that a fixed pole with the mass supported on a cable from the bottome of the pole? What is the solid, angled line from the top of the pole to the ship? What is the coordinate theta supposed to represent?

Whatever this system is, it looks like you have at least 4DOF involved, so it is going to be a bit messy.
 

FAQ: Movement in a non-inertial referential

1. What is a non-inertial referential?

A non-inertial referential is a frame of reference that is accelerating or rotating, meaning that the laws of motion do not hold true in this frame.

2. How does movement in a non-inertial referential differ from movement in an inertial referential?

In an inertial referential, objects move in a straight line with constant velocity, whereas in a non-inertial referential, objects may experience accelerations or changes in direction due to the frame's acceleration or rotation.

3. What is the Coriolis effect and how does it relate to non-inertial reference frames?

The Coriolis effect is a phenomenon where an object in motion appears to be deflected due to the rotation of the Earth. In a non-inertial referential, this effect can be observed as the result of the frame's rotation.

4. How do we account for movement in a non-inertial referential in scientific experiments?

In scientific experiments, we must take into account the acceleration and rotation of the non-inertial frame in order to accurately measure and analyze the data. This can be done by using mathematical equations and calculations to correct for the frame's movements.

5. What are some common examples of non-inertial referentials in real life?

Some common examples of non-inertial referentials include a merry-go-round, a rollercoaster, a car turning around a curve, or a plane making a turn. In each of these cases, the frame of reference is accelerating or rotating, making it a non-inertial referential.
