Presenting Data Assignment A submarine is initially traveling due north at a constant 10 knots (nautical miles per hour (nm/hr)). An accelerometer mounted on the submarine measures its acceleration in the cast and north (x and y) directions every minute. Acceleration data for a period of time during the first 30 minutes of operation is given in ordered triplets, (t, au ay), as: (5, 20, -10), (6, 50, -25), (7, 100, -50), (8, 120, -40), (9, 80, -10), (10, 10, 0), (20, 100, -100), (21, 200, -400), (22, -100, -600), (23, -500, -400), (24, -300, -200), (25, -100, -50) where it is time in minutes, a, and a, are the acceleration in units of nm/hr in the x and y directions, respectively. For any period of time in which the acceleration is not given, it can assumed to be zero. Using the trapezoid rule, integrate the acceleration with respect to time to determine the sub's velocity in each direction and then integrate the velocity as a function of time to determine sub's position in each direction. Calculate the magnitude of the sub's velocity as a function of time. Plot the sub's velocity as a function of time and plot the sub's path as traveled in a North-South-East-West coordinate system. Determine and report the sub's minimum and maximum velocity magnitudes, final position relative to the starting position, and final heading (direction of velocity in degrees as measured clockwise from north) at the end of 1/2 hour. Write up your analysis in a two page technical memo. Make sure to introduce the problem, present the appropriate equations of integration, present the two required graphs and the associated motion parameters, and make some reasonable observations and recommendations. You may use MATLAB or Excel to create your graphs. Use 11 point Times New Roman font with 1.08 line spacing and 1.0" margins on all sides.
