Answer to Question #69289 in Physics for Ritesh

Question #69289
A body of mass 0.2 kg is suspended from a spring of
force constant 100 N/m. The frictional force acting
on it is 60 Newton, Write down the equation of
motion and calculate the period of free oscillations. If
a harmonic force F = 20 cos 20t is applied,
calculate the amplitude of forced oscillations.
