A mass attached to a spring is pulled downward and released. The displacement of the mass from its equilibrium position after t seconds is given by the following function, where d is measured in centimeters (see the figure). The length of the spring when it is shortest is 15 centimeters, and 35 centimeters when it is longest. If the spring oscillates with a frequency of 9/5 Hertz, find d as a function of t. d = A cos (?t) d=_____
