Answer to Question #276491 in Civil and Environmental Engineering for Fernando

Question

A spring is such that it would be stretched 8 in by a 4 lb weight and a damping force of

magnitude 0.5|𝑣| is added because of immersing the body in a thick liquid. Let the weight be

attached to a spring and pulled down 5 in below the equilibrium point. If the weight is started

with an upward velocity of 3.5 flt/sec, describe the motion. No impressed force is present.

Answer 1

Answer is given below with diagram of waves produced in the spring during damping force:
