Question 1133001: A person bungee cord jumping oscillates up and down. The distance from their highest point to their lowest point is 10m. and the person takes 7 s to complete 2 cycles. For the first few cycles the distance from the mean position, d metres, with respect to t seconds, is modelled by a cosine function.
a)Sketch a graph of this function for two cycles.
b) Write an equation that describes the distance of the person from their mean position as a function of time.
c) at what height is the person after 9 seconds?
