Final answer:
The formula for calculating phase shift in the context of periodic functions is ϕ = 0.00 rad. It represents the amount by which the function is shifted to the right.
Step-by-step explanation:
The formula for calculating phase shift in the context of periodic functions, such as a cosine function used to model a block on a spring, is ϕ = 0.00 rad. It indicates the amount by which the function is shifted to the right. In the equation x(t) = A cos(wt + ϕ), where t is time, w is angular frequency, A is amplitude, and ϕ is phase shift.
Note that sine and cosine functions differ only by a phase shift, so either can be used to model the motion.
It is important to determine the angular frequency first in order to calculate the maximum velocity and maximum acceleration.
