pls answer hand written also ok

Next suppose we give it 7 impulses with ( = 4 2jn 2 Y(s) = - Ejoe WS + 2 ((s + 0.1)2 +4) ( (s + 0.1)2 +4) Notice that as w increases the time between impulse decreases and they occur more often. a. Find the equation for y(t), show all your work. b. Give the piecewise function for y(t) and show its graph on the domain [0, 25] seconds. I
