Homework Help: Math

Posted by Katlyn on Monday, March 25, 2013 at 5:46pm.

An object suspended from a spring is oscillating up and down. The distance from the high point to the low point is 30cm, and the object takes 4s to complete 5cycles. For the first few cycles, the distance feom the mean position, d(t) centimetres, with respect to the time, t seconds, is modelled by a sine function.

Find the amplitude, vertical shift, phase shift and k value and period. Do all calculations and then make your final equation.

Can u please help me with this pne cuz there are a lot more and i don' t understand any of them please help meeee!!!:(
