Q) A particle of mass 4 kg rests on a smooth horizontal surface and is attached to a horizontal spring. The mass is then displaced horizontally outwards from the spring a distance of 26 mm and then released to vibrate. If the periodic time is 0.75 s, determine (a) the frequency f, (b) the force required to give the mass the displacement of 26 mm, (c) the time taken to move horizontally inwards for the first 12 mm.
