%% Givens
m=2; %kg
k=200; %N/m
x0=0.05; %meters
x_dot=2; %m/s
%% Solution Part A
Wn= (k/m)^0.5;
c= (2*m*Wn);
Cc= (2*m*Wn);
Zeta= c/Cc
%% Solution Part B
for t=0:10
C1=x0;
C2=x_dot+Wn*x0;
x = @(t) (C1+C2*t)*exp(-Wn*t)
end
I want my function to plot with respect to time. The ezplot generated begins the x-axis at -5.5, however since this is a plot of response with respect to time, -5.5 does not exist. Long story short, how can I make my plot go from a certain time range of 0s to 10s. Thank you

fplot(x,[0,10])
