% converting m/s to mph, 1m/s = 2.237 mph
A = 5*(2.237^2)/2.237;
B = 0.4*(2.237^3)/(2.237^2);
V = 0:0.2:250; % this is velocity in mph, since we have changed
constant values to mph.
P = A*V.^2 + B*V.^3;
P_hp = P / 745.7;
plot(V, P_hp);

You might find the following built in commands useful: length, plot, xlabel, ylabel, title, legend, fzero, plot, disp, axis, axes, min, max. 1. A spring-mass system has the following position y(t) and velocity v(t) functions: y(t) = e −0.5t sin(2t) + √ 3e −0.5t cos(2t) v(t) = e −0.5t (2√ 3 − 0.5) sin(2t) − 0.5(4 + √ 3)e −0.5t cos(2t) where the units are in...

I need help in MATLAB. I'm working on a circuits lab report and I want to plot the derivative of an input signal. The circuit is a differentiator OpAmp. It is receiving a triangle wave as an input and should output a square wave. (I've included my existing code.) The output formula is: Vout = -(Rf)*C*(dVin/dt) Where Rf is feedback resistance: Rf = 1*10^6; and C = 1*10^-6. EXISTING CODE: %% This section is copied, and then modified from another...
