Question

Need some help with the following MATLAB question:

MATLAB Program Problem FA rocket is vertically propelled up during the first 1.5 secs with a speed of v(t) = (a-g) * t and then falling down with a speed of u (t) =-g * t for the following 2.5 secs. Using "for-end" statement with an inner loop of "if-else-end" statement, compute v (t) during 4 secs with an increment of 0.1 secs. Plot v (t) vs. t during 4 secs (i.e. t-0:0.1:4.0). Add the labels of axes and the tile of plot. Use lines with symbols to represent a curve.

Explanation / Answer

g=9.81;

x0=0;

y0=0;

x=t;

y=v(t);

for t=0:0.1:4;

if t<=1.5

v(t)=(a-g)*t;

else

1.5<t<=4

v(t)=-g*t;

end

end

figure;

plot(v,t);

title('v(t) vs t');

xlable('time(s)');

ylable('velocity');

grid on;
