Please answer this problem FULLY with detail steps on how to slove. My professor normally has us answer these questions by hand, and for complex imformation to put the rest into Excel. So, the handworked steps and solutions would be greatly apprecited. Thank you! For the following problems you must develop a diagram to show the situation, include a brief problem statement and clearly show the energy balance equations you are using (start from the appropriate form of the energy...

Elementary Differential Equation Unit Step Function Problem Project 2 A Spring-Mass Event Problenm A mass of magnitude m is confined to one-dimensional motion between two springs on a frictionless horizontal surface, as shown in Figure 4.P.3. The mass, which is unattached to either spring, undergoes simple inertial motion whenever the distance from the origin of the center point of the mass, x, satisfies lxl < L. When x 2 L, the mass is in contact with the spring on the...
3. First order ordinary differential equation) A solution containing 90% by volume of alcohol (in water) runs at 1 liter per min into a 100-liter tank of pure water where it is continually mixed. The mixture is withdrawn at the rate of liter per min. The alcohol volume in the container, Nis given as AV-10 100 0515201 dr 10 We would like to predict the alcohol volume in the tank, N as a function time, t. Use At-1 s. Solve...
Problem Set A Problem 6. (20%) A ordinary differential equation for a mass-damper-spring system is following. The mass m 1, damping coetfic e initial position y(o) O, and the initial velocity i constant k 3 and force 10, all are in appropriate units.
