Answer to Question #54669 in Physics for Kamal Agarwal

Question

Consider N identical masses connected through springs of same force constant k. The free
ends of the coupled system are rigidly fixed at x = 0 and x = l. The masses are made to
execute longitudinal oscillations.
i) Depict the equilibrium configuration as well as instantaneous configuration.
ii) Derive the equation of wave motion.
iii) Calculate the velocity of wave when a force of 500Nacts on a system with mass per
unit length 0.25kgm .
