y''(t)= -y(t) + s(t)
y(0) = y'(0) = 0
solution: y(t) = sin(t)
Explain the physical meaning of the DE above and its solution in terms of the mass-spring system.
Doubt in this then comment below.. i will explain you..
.
Please thumbs up for this solution...thanks.
.
given is
y''+y= s(t) ....
Here , we see that damping coefficient is 0 ....it means there is no resistance in motion...
Also , y(0)=0 ... It means spring starts from equillibrium position..
y'(0)=0 ...it means that spring starts motion from rest ..
S(t) is the external force acts on the system
Its solution is sin(t) ..
This is periodic function whose amplitude is 1 , frequency is 1 and period is 2*pi ..
Spring moves up and down between fixed position ... No decreament in its amplitude takes place
