Question

F(t) = 20 cos ot. Calculate (i) the position of the mass at any time, measured form the
equilibrium position and (ii) the angular frequency for which resonance occurs. (5-5)
5. a) The displacement of an oscillator is written as
y(t) = a sin (oto)
whereas the equation of a wave is written as
y(x, t) = a sin (ot - kar)
he differences between the two.
