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 function d = A cos(ot), where d is measured in centimeters (see the figure). The length of the spring when it is shortest is 13 centimeters, and 23 centimeters when it is longest. If the spring oscillates with a frequency of 0.4 Hertz, find d as a function of t. d =

Expert Solution
Step 1
Length of spring when it is shortest
Length of spring when it is longest
Frequency of oscillation of the spring
Step 2
Since the shortest and longest lengths of the spring are 13 cm and 23 cm respectively, we can say that the spring oscillates between 13 cm and 23 cm.
Hence, the spring oscillates in total 10 cm of distance.
Thus, we can say that the amplitude of this oscillation is 5 cm.
