Write a script "YourLastName_HW2.m", which 1. calculates the speed of a tsunami in meters per second (m/s) according to the formula V =gd where d = 2500 m is the depth of the ocean in meters, g=9.81 m/s. 2. converts the speed of the tsunami wave from m/s to miles/h using an external function "MpsToMilesph.m". The function should have velocity in m/s as an input argument and velocity in miles/h as an output argument. 3. calculates how far, in miles, the wave will travel in 8 hours. 4. uses the disp function to print the tsunami speed in miles/h, the travelled distance in miles, and corresponding parameter names and units. 5. Includes housekeeping commands clear and clc. 6. Includes comments. 7. has only one command per line. 8. makes sure the output is suppressed except when the disp function is used.
