Welcome guys .Here are some problems of SHM for those who are currently practising SHM. Q: A loudspeaker produces a musical sound by means of the oscillation of a diaphragm whose amplitude is limited to 1.00 μm. (a) At what frequency is the magnitude a of the diaphragm’s acceleration equal to g? (b) For greater frequencies, is ‘a’ greater than or less than g? Take g = 10 ms-2. Q: What is the phase constant for the harmonic oscillator with the velocity function v(t) given in figure if the position function x(t) has the form x = Acos (ωt +ф)? The vertical axis scale is set by vs = 4 cm/s. Q: The equation of motion of a particle started at t=0 is given by x = 10sin(10t + п/3), where x is in centimeter and t in second. When does the particle (a) first come to rest (b) first have zero acceleration (c) first have maximum speed? Q: Consider a simple harmonic motion of time period T. Calculate the time taken for the displacement to change value from half the amplitude to the
