Cut a signal in Time domain

Hey ,
for a project i have to generate a sinusoidal signal(force signal) and a second signal with a step function(speed signal) , then try to get the amplitude of the force signal and the phase difference to the speed signal. In which i have to cut the force signal in time domain in the same time of the step of the speed signal , and then show the amplitude and phase at that point using FFT. any Ideas ?

see example below
clc
clearvars
t = (0:0.01:2);
y = cos(2*pi*5*t);
% select second hal of signal , t>= 1
ind = (t>=1) ; % logical array
t2 = t(ind);
y2 = y(ind);
plot(t,y,t2,y2,'r')
