Analyze the problem statement to prepare a free body diagram of the submarine (shown in

Figure 1).

Use the prepared free body diagram to find the equation of motion for the submarine.

Prepare diagrams of the model under various conditions in Simulink and run each simulation

for 30 seconds.

Use the given damping coefficient values to determine the stiffness values.

Run each simulation using the stiffness values calculated in step 4. Determine the maximum

velocity of the submarine and the maximum force and elongation in the towing cable for the

system using each calculated stiffness value.

Plot all results, then compare the velocity, towing force, and elongation for each set of

conditions.
