For a damped harmonic oscillation, the equation of motion is 0, 2 2 + g + kx = dt dx dt d x m with m = 0.25 kg, g = 0.07 kgs−1 and k = 85 Nm−1. Calculate (i) the period of motion, (ii) number of oscillations in which its amplitude will become half of its...

The oscillations of two points x1 and x2 at x = 0 and x = 1 m respectively are modelled as follows: y1 = 0.2 sin 3pt and y2 = 0.2 sin (3pt + 8 p ) Calculate the wavelength and speed of the associated wave.
