Problem 1: A) Energy Methods Look at the below system. Using the conservation of energy method, solve for the governing equation of motion for the system. Put a box around your final answer. Also, put a box around your equations for the potential and kinetic energy of the system. Assume the system’s springs are initially unstretched (i.e., assume that there is no gravity until t = 0 [s]).    B) Numerical Methods Using ode45, your answer to problem 1, and the following initial conditions and system parameters, plot the response of the above system in MATLAB for at least 5 complete oscillations, and no more than 20 oscillations. m = 72 (if your last 2 digits are 00, than assume m = 1) [kg] k1 = 673 [N/m] k2 = 880 digits of your student ID [N/m] g = 9.81 [m/s2] x0 = 0 [m] v0 = 0 [m/s]

Can you please answer number 3 and show all of the steps to the solution

Answer is also mentioned in picture containing the question. Kindly check the answer before submitting the solution.  Wrong solutions have been submitted very recently earlier for same question.  Kindly ensure proper steps and matching the answer.

Read and analyze each word problem and give what is/are required. Write the detailed solution If possible, express your final answer in the form u(t)= Rcos(@,t – 8). 2. A spring is stretched 3 in by a 5-Ib weight. Let the weight be pulled down 4 in below equilibrium and then given an upward velocity of 8 fps. Describe the motion, then find the maximum displacement of the motion.
