*Hi, please help me with this differential equations questions and please show the full solution. Thank you very much. *
Question 1.) A load weighing 2 kg is attached to a spring. If the damping force is 5.5, spring constant is 4.2, and external force is sin(t), and the load is released from rest 0.2 inches below its equilibrium, determine the displacement of the object at any time t.
I need a clear step by step answer please :)

Suppose identical solid spheres are distributed through space in such a way that their centers are lie on the points of a lattice, and spheres on neighboring points just touch without overlapping. (Such an arrangement of spheres is called a close-packing arrangement.) Assuming that the spheres have unit density, show that the density of a set of close-packed spheres on each of the four structures (the "packing fraction") is: fcc: bcc: √√2/6=0.74 √√3/8=0.68 SC: π/6=0.52 √√3/16=0.34 diamond:arrow_forwardI1 Give an example how it is applied in molecular dynamics simulation and Monte carlo simulation?
