Question

Use only matlab to do this nothing else. Please attach picture of all the steps. Thanks.

Answer 1

time = zeros(100,1);
for i=1:100   %time at intervals of 0.1 seconds
    time(i,1) = i*0.1;
end

velocity = zeros(100,1);
acceleration = zeros(100,1);
distance = zeros(100,1);
%calculating velocity at the intervals
for i=1:100
    t = time(i,1);
    velocity(i,1) = -0.011*t*t*t - 0.2*t*t + 2.4*t + 2;
    acceleration(i,1) = -0.033*t*t - 0.4*t + 2.4;
    distance(i,1) = 18 - 0.011*(t^4)*0.25 - (0.2*(t^3))/3 + 1.2*(t^2)+2*t;
end

figure
subplot(3,1,1);
plot(velocity(:,1), time(:,1));
xlabel('time (s)');
ylabel('velocity (m/s)');
subplot(3,1,2);
plot(acceleration(:,1), time(:,1));
xlabel('time (s)');
ylabel('acceleration (m/s2)');
subplot(3,1,3);
plot(distance(:,1), time(:,1));
xlabel('time (s)');
ylabel('distance (m)');
