Answer to Question #78175 in Mechanics | Relativity for Prerana

Question

A body of mass 0.2 kg is suspended from a
spring of force constant 100 Nm-1. The
frictional force due to air drag acting on it is
5v newton. Write down the differential
equation of motion and calculate the
period of free oscillations. If a harmonic force
F = 20 cos 20t is applied on it, calculate the
phase lag in the steady state.
