Answer:
y(0) = 0.25 feet
Step-by-step explanation:
We are given the following information in the question:
The displacement from equilibrium of an oscillating weight suspended by a spring =
where y is the displacement in feet and t is the time in seconds.
Here, cos is in radians.

y(0) = 0.25 feet
2) t =
3) t =
The negative sign indicates the opposite direction of displacement.
