Question

At time t 0, when a rocket's engine shuts down, the rocket has reached an altitude of 500 m and is rising at a velocity of 125 ms At this point, gravity takes over The beight (m) of the h(t) = -4.9t2125t +500 for t > 0 rocket as a function of time (s) is Construct a table that displays two columns, time (t) and height (h) of the rocket. a. Create a vector t for time from 0 to 30 seconds in 2 second increments b. Create the corresponding vector h for height, which is computed from t with the above formula. Construct a table from t and h c. d. Display the table using fprintf with the appropriate columns headings and title Indicate units in the column headings Attach File Browse Content Collection trowse My Computer

Answer 1

the matlab code is written following the steps a to d in the question. array is created in the first step manually, then calculated the height using the formula given in the question, table is created and taken output using simple table command, the column title is edited using the 'VariableNames' command, fprintf is used to print the title of the table. code and the output is given below. (note: every command starts with % is explanations to next command)

Code:

clear all; clc;
% initialization for time
t=[0;2;4;6;8;10;12;14;16;18;20;22;24;26;28;30];
%the height of the rocket
height=-4.9.*t.*t+125.*t+500;
% table created
T=table(t,height);
% fprintf statement
fprintf('The table of height of the rocket v/s time\n')

% to print the table with appropriate column headings
T=table(t,height,'VariableNames',{'time_seconds' 'height_meters'})

Output:
