Q.3 (Applications of Linear Second Order ODE): Consider the 'equation of motion given by ODE #1+w2r= Focos() where Fo and wty are constants. Without worrying about those constants, answer the questions (a) (b). (a) Show that the general solution of the given ODE is 2 pts o(t) :- 1+= cos(wt) + sin(wt) + cos(nt). A) Find the values of u and if the initial conditions are (0) and (0) solution is part (a) can be written explicitly as a(e) -...
AP1. Consider the pendulum system shown below, where L = 0.7 meters, m = 1.5 kg, g = 9.81 m/s and e(t) is measured in radians. Pivot point Massless rod ! Lom, mass a. Show (by hand) that the motion of the pendulum is represented by the following dynamic equation: (t) + sin(()) = 0 b. Note that the differential equation above is nonlinear. When the equation is linearized about the equilibrium point (0) = 0, the linear time-invariant (LTI)...

3. Consider the Linear Time-Invariant (LTI) system decribed by the following differential equation: dy +504 + 4y = u(t) dt dt where y(t) is the output of the system and u(t) is the input. This is an Initial Value Problem (IVP) with initial conditions y(0) = 0, y = 0. Also by setting u(t) = (t) an input 8(t) is given to the system, where 8(t) is the unit impulse function. a. Write a function F(s) for a function f(t)...
