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 m/s. The height of the rocket as a function of time is 9.8 2 ( ) 125 500 for 0 2 h t t t t      (1) Create a time array time from 0 sec to 30 sec with an increment of 1 sec and a corresponding array for the height height. You don’t need to display the arrays. (2) Using the max()command determine the time and the height of the rocket when it reaches the maximum height, i. e. t_max and h_max. (3) Plot the height of the rocket from 0 to 30 seconds using the command plot. Make sure to add labels for x and y axes of Time(sec) and Height(m), respectively. (4) Use the disp command to output time and maximum height using t_max and h_max obtained from (2) and a function num2str(num). The following is a sample output. Note that you need to use [ , , ] for disp function to display multiple elements
