Answer to Question #149345 in Physics for Reanna Mol

Question

A mass m is subject to a resistive force –bv and a driving force given by F=F_0 cos⁡〖〖(ω〗_d t)〗. No restoring forces act on this system.

Develop the differential equation of motion.

By assuming a steady-state solution of the form x(t)=A cos⁡〖(ω_s t-δ)〗 and using the complex exponential method, determine the amplitude A and phase lag δ for this system.
