a)Extract the data from the two columns into separate arrays named time and distance.
b) Determine the velocity and acceleration of the rocket. Use a FOR loop or as many as desired, nested or not, and two nested IF branching structures to solve the question.
clear memory
clear all
clc
time=[rocket_launch(:,1)]';
distance=[rocket_launch(:,2)]';
for k=1:length(time)
for j=1:length(distance)
end
end
i'm not quiet sure how to write the two nested if branching structure inside the for loop structure

How are you instructed to calculate velocity and acceleration? By differencing points? By curve fitting with the rocket equation and differentiating the curve? What is the method you discussed in class?

by differencing the points

Hints for using a difference method:
Velocity = ΔPosition / ΔTime
Acceleration = ΔVelocity / ΔTime
To get the delta values, just subtract adjacent points.

Thank you. I finally got it right using the hint you gave me.
