Spring An object suspended from a spring is oscillating up and down The distance from the nigh point to the low point is 30 cm and the object takes 4 seconds to complete 5 cycles For he first few cycles the distance from the mean position d t centimetres with respect to the ime t seconds is modelled by a sine function Sketch a graph of this function for two cycles Write an equation that describes the distance of the object from its mean position as a function of time
